Don't double post, especially if you know it's wrong. -_-
Anyways, these are nothing to be proud of. They really aren't very good, being generally quite messily done. Honest-to-God truth is I can't find a single one that is neat and properly cleaned up of all bad pixels with the proper coloring, shading and with all the parts on properly.
You don't make the pasted on body parts look natural or anything, not even properly recoloring them a lot of the time. They just look like you glued random body parts onto with without a second thought. You have to put in a bit more effort into your sprites. Look out for shading, don't reverse body parts because it just makes them look messed up, but if you do edit the shading. Light is always coming from the top left hand corner of any sprites, so the highlights and shadows have to correspond to it.
I'm not going to comment on every single sprite because there's really no need to, plus you would find it extremely discouraging if I had to point out every specific problem with them, and I can tell you now that each one could be about twice as good as it is now.
Sorry, but it's the honest truth. Go read the tutorials (you can't miss the Sticky full of them) and practice a bit more. Have a look at some other sprite collections to get a better idea of what you're doing wrong and how to improve.
Good luck,
