presentation needs work, that's about it...size of the print maybe a little bit smaller would do.
and the white outline seems like it's there because you might not know how to get rid of them in photoshop..so fix that.
i understand the kind of drawing that this is, so i don't need to get uppity about you "not knowing how to draw" etc...it's fine...but that much that i have said needs the work.
I'm guessing this isn't complete? If it is, the left arm of the airplane, going behind the head, is way to long. Either vector the drawing or clean up the lines, you can still see a white ring around everything and some marker strokes in the black areas. It needs some dimension or at least more black so that the white isn't as glaring against the red shirt.
