Here's the initial Alchemy sketch. It's not totally arbitrary in that you can get certain shapes to go in specific directions as you draw, but a lot of what happens is completely random. In this case it is supposed to represent some sort of armored soldier -
I used this as the starting point for the painting below and as you can see, quite a bit of what was in the initial sketch survived to the finished piece.
What's cool is that there are dynamics with the shapes and how they interact that I would have never come up with on my own and I think they add a lot of visual interest. On the other hand, none of it looks very practical and I would hate to have to attempt to draw that armor over and over and from different angles.
Also - Alchemy Space Lizard would be a kick-ass name for a band.
