Don''t worry about it, most professional game programmers suck at art. There''s even a derisve term for it that the artists at game companies use for the placeholder art that programmers do. Oddly enough it''s called "Programmer Art". My recommendation is find an artist. You don''t have to do it all yourself. The pros don''t. In fact, at most of the game shops I know personally artists and modellers outnumber programmers 3 to 1 (or more).
