Before you start I would like to say that there is no definitive guide for drawing, it is something very personal down to the way you hold your pencils and pens.
Step 1: Materials you will need
For now the drawing is kept simple and yes if I get good feedback I will add more instructables as follow ups that as the pictures below show will take you up as far as the level I am at. Unfortunately I will have to become a better artist when that point in time comes along. I would be able to give better examples and plan to add them when my art coursework finally comes back to me from moderation as I was under special circumstances this year due to my fathers passing away.
In the meantime these two images will have to suffice, the first being a caricature of Angus Young, or was it Bon I did too many caricature in one night and the second is from my coursework that shows a good example of shaped cross-hatching on the lighter's body (best ignore the rest I was firing out a page a minute for a deadline)
Step 2: Jump right in
For now I'm going to go with a sketching method for lines using short strokes. The reason for this is that sketching tends to be the base of any drawing, painting or print.
First pick the object you want to draw, maybe something simple but with minor details that make it interesting. For my example of this part I am using a screwdriver because it's an instructable and the dremel's a bit too complicated to draw and document at the same time.
So once you've got the object you're wanting to draw, make yourself a light outline of it, including line inside the outer part.
NOTE: Ignore the darkness of mine as I had to use an extremely dark pencil (8B) throughout this to make sure everything showed up on camera well enough.
Step 3: Got the outline?
Here you're only trying to get the shape of the main shadow using a lighter shade, this gives you a better idea of how to shade your shadows within this.
Step 4: More shadowing and tone
Here your drawing should be starting to take on some depth.
Yes I do know my screwdriver is squinty but I have a very rough take on drawing.
Step 5: Starting to look more like a drawing?
You might have noticed that I still havn't told you how to hold a pencil 'right' or shade the 'good' way, this is because in this first lesson you are learning to get to grips with your tools and in particular pencil holding is a null point as people are individuals and unique in so many ways. To explain I'm using stories about how I learnt how to draw a total of 4 times in life, specifically the most recent.
The year before last I broke my arm at a party (whiskey + trampoline) and when I came in to art fully healed I knew I was going to have hell of a time getting any good work done for the end of term deadlines. This is because drawing has a lot to do with how you move and hold your pencil, specifically when you break a bone in your arm the geometry of it changes alot and unconciously your skills are completely based on your subconcious knowledge of that geometry. As far as artistic talent goes you have it or you don't but either way knowing your own hands will help alot (not in that way though...).
Step 6: Personal touches
You can choose to do alot to your image here and If you've already gotten the hang of your basic drawing skills then remember details work the same on a smaller scale.
Now we move on to something a bit more fun.
Step 7: On to pens
An inky pen (rollerball) ones are preferable as next time I will illustrate the uses of a biro for drawing
Step 8: Inventing the character
Now we're trying to get a more solid line look to the drawing so sketching is out and slower more deliberate movements are necessary.
I make the garment's style or state by starting lines like so.(it's a top hat by the way)
Step 9: Get a hat!
If you look how the hat below is done you can see the basic idea for what you're going for.
By the way it doesn't need to be raggedy like mine your man should hve is own distinct and silly style.
Step 10: Start the person
I know right now it looks stupid but your ears are always visible so bear with me and you'll see next step.
Your person's eyes and ears should reflect who he/she is like thick glasses, beady eyes, etc.
Step 11: Adding features
Oops I had a wee bit of confusion remembering what was face and waht was hair, thankfully his hair will be black anyway.
Step 12: (optional) this step is for hair the same coulour as your outlines
Step 13: Facial details and expressions
I would tend to go for funny looking teeth most of the time as it adds alot of character to out character.
Step 14: Adding the finishing touches
For colour these guys really suit simple block colours though with just a pen they make a nice time filler/waster...
Step 15: A quick Intro to cross hatching
Step 16: Create a basic hatch
First draw a rough circle, in the circle I want you to make a series of line like the ones in the picture.
Sorry for the teacherish way of doing this part it's just a good way of showing what we're trying to do.
Step 17: Now the other way up...
Step 18: More shades
Step 19: Smoothing the shades
You'll notice this is very rough looking and quite large, this is because it is an example and in practice this is usually done with smaller hatches and a very fine pen. Also try your best not to 'zig-zag', where you scribble rather than create seperate lines, it make the hatch uneven and there are waves of the ends of scribbles through the drawing.
Step 20: Finally add some shaping to the ball
As I said before for a better version of cross-hatching look at the first step of the instructable
