I like the angry possessed nut weilding critter lol
I do a lot of toons around my home phone table and I
have a book that I do them in as well when I cant get one
off my chest and need to refine it. I get stuck drawing
similar characters for a while then move onto other styles
or methods. Scratching ink and washed colour looks good, especially
no black ink bleeds in raw colours when using the computer.
Try and draw the same one you like the most with different cells rotating around the x axis and you get a better idea of how they will be in 3d as well as refining them in your mind. Iguess thats taking simple sketching a bit too far but yer im hungover so thats my excuse
