Thanks for the comments guys!! I really appriciate it. The second drawing is almost done, but i still have to color some stuff and then you can see them =D.
@kasumiGirl: I read what you said, and I really appriciate the advice, but what you mean by "I think anything is particularly wrong with your drawings"? I'm kinda stuck there imo.
EDIT
Does anyone know any good stores that have manga art supplies like those special pens or coloring stuff? I'm thinking of the Art institute of Chicago (near where I live of course), or Borders
. Maybe you guys have any suggestions?
