I think you outta just add all your small weapons together on one sheet (unless you want to use them as avatars, and even then the small icon can be changed depending on the one you want to use).
I suggest you to post it in the forum before adding it into the gallery, so you can receive more useful critics and comments :)
asukicco - I'll try that next time.
Blackbeltdude - Yeah, I'll do that.
