Aaaand it does...seriously, even if you're forced to use less than perfect sprites, at least making them consistent really helps. Seriously, having a shitty sprite next to a really detailed or large one makes it look shittier, and mixing style MAKES the eye pick out flaws in all of them.
How about, instead of bitching, use the critisism to get better. There's only two reasons to post things:
1: For input to improve it.
2: To stroke your own ego.
You seem to have been going for 2, but you really need 1.
