I think this is really cute! I just wondered, have you ever thought to trace your drawings in a vector art program like Illustrator after scanning them in before you do the coloring in bits? It makes the drawing look a lot more 'finished' sometimes (since line drawings by hand are always prone to a bit of wobbly lines, I always had that issue!). I always felt like it made my art look more cool that way. Just a thought! I love it anyway, but I thought maybe if you hadn't considered it, it could be useful!
