a couple of years ago I started spriting a bunch of weapons but I didn't finish them due to lack of experience but, now that I have sort of a clue of what i'm doing in regards to shapes colors and shading i think these turned out fine. the ideas/names are from aqw,
the outlines look rough on some parts but it cant be helped, and i can understand what you wanted out of this, and im not going to dictate and say "more contrast" or what ever, but it does need just a tad bit more because... metal. other then that these are some old sprites with a recent touch up, really cant be helped and they are some great designs man!
