At first my plan was to make a clay model then cast it in silicon then concrete for his driveway but I got to such a detail level that I wasn't certain the cast would take so I have given it a bronze like finish.
When I have the time I will make one each for my mum and dad in concrete to put at the end of the driveway!
This is my first instructable so if you have any questions/critisims then let me know.
Step 1: Image Study
The green lines are the features that need to be just right and the red lines are all the bumps that make my dads face HIS face. :-)
Continue adding detail.
Remember the shapes you picked out from the photo.
My dad was in a seious accident in his yoof which led to quite a bit of scarring. This led to it being easier for me to pick out features. However i had to get them in exactly the right place.
I stopped referring to the photo once I had everything in the right place then changed a coupla details based on memory. Ultimately, its what YOU see in that person that represents them rather than a photo.
It sorta helps that I look like him too!
Stick the brush into every nook and cranny.
I used liquid enamel in brass with a soft brush to stipple all over the bust till it looked how i wanted it. The trick is to have a higher shine on protruding bits and leave black in the deeper creases. This is the effect of an old polished statue. I thought it looked too brassy so I used a spray on Antique Gold to darken it a bit. I sprayed it on then quickly polished it in with a sponge.
When dry, polish lightly with a soft cloth.
