I don't have much of an eye for color, so I'm going to force myself to start to work with it more with the hope that I'll slowly get more comfortable with it.  Here's a simple sketch I slapped some color onto.  It'll be the first in a series of images of this sort.  They will be quite rough, as my aim right now isn't to create nice, fully polished images, but to get used to the initial phase of choosing colors that go well together.  I'll try to increase the complexity over time and then I'll try to do some finished colored pieces.
