Dude, I gotta say.... love the sketchyness...
Reminds me of my work to an extent (hopefully I'll be able to do something soon :/). Anyway, really like the shading and colors, usually that's my weakspot :c It's a bit dysproportionate though, well more like it doesn't really seem relatively proportiontionate... still really like it :J
What do you use though, photoshop or something?
