Gasp!!!
Isometric views with redrawn frames!
*applause* If something like that is done I just expect a direct top down view rotated around. Maybe I'm stepping my bounds, I don't usually pay much attention to the gun sprites at all so maybe my expectations aren't very well founded.
In any case nice work on that shotgun. It a bit..ah..gigantic though.
The shading could use some work on the up/down views. Try making the entire left side of it the lighter color you have in there, instead of adding as many colors as you do and leaving the light shade to only a few scattered pixels. It's also really tough to see the transition from the end of the barrel to the top, the lighter color on top would show it off better and give more distinction to the form.
With the top set...
That shark is fun

Do you plan on doing anything more with the bunny? Animation? Eh? Eh? You should totally animate it
I think I like the wreath the best. It could maybe use a little work on the bow, though. Maybe you could make the underside of the bow a little darker? It could use a little extra contrast, but not so much as to separate it's style from the rest of the piece.
