Step 1: Stuff You'll Need
. Paper (any)
Step 2: Drawing The Head
Start with a circle. In the image there are rings that go vertical and horizontal. Inside the circle. You don't have to put them there, but it will help with the rest of the head.
When you have that part done. Try doing a curved line for the top part of its dome like head. Use the middle line inside the circle and arc back. Take the horizontal line and make a jaw with a chin. With that same horizontal line make the dome top were the shiny or detailed part will be cut off. When you get done with that, erase all of the lines in the center of the circle to make it clean. Add the mouth and the lines that separate the mouth in segments. Add some teeth to it. NOTICE that they have some human like teeth in the front. The rest are sharp.
Sorry that the third photo is blurry.
Step 3: Drawing The Arms And Body
Draw a neck and at the base of the neck. You draw a giant arc for the shoulder. Next to the jaw line is a half arc for the other shoulder. Behind the first shoulder is a spike or tube like thing. The spike has tinier spikes on the top of it. The tubes have oval looking things that have lines. This is some detail, but I will get into further detail later. Draw little circles inside the arc where you want the beginning of the arm to start. Draw a line. Draw another circle at the end of the line. Making it the joint and where the arm bends. Draw another line and circle at the end of that. For the hand base. Repeat for the other side.
For the body. See how it has a bigger base or wider stomach. It's a warrior so it's a bit bigger than a lurker, yet smaller than a spitter. The block lolling things going down its chest are the rib connecting parts.
