I can not draw, but I can do simple 3D models.
Here is a rendering of one I've done recently.
I can use MakeHuman to generate models of human characters, then use blender to model clothes, rig and skin the clothes, then pose the clothed characters and render them.
TacocaT can actually draw, though (better than I can, at least). If you want sketchy, comic-type characters and don't mind doing a little ego stroking, you may also try ISentinelPenguinI.
