Here's an image sequence showing the progress of an illustration from b/w sketch to color composition to final art. If you look close you can see that some things were changed along the way, which is why taking these steps can be really useful.
I'm thoroughly engrossed in this project. Its a challenge to pick out sketches to share that aren't too revealing. There are ones I really really want to show, but not yet. So again, another rough sketch with no context.
