honestly I think this looks good and pretty well balanced, for what it is though the only suggestion I would make would to instead stick with a strict bunny theme and go by each weapon personally to make it theme'd as such. for example putting a rabbits foot on the round of the scattergun

It is too black

My suggestion, then: Instead of making it random images, choose two of the items on that list (I'd take the crystals and the magic-circles) and work on making a texture that uses both of those elements not as repeated patterns, but rather as one consistent theme. Perhaps the main-texture is an enchanted crystal surface coated in scratched-on magical symbols that glow from the cuts.

Then, touch up on the secondary texture. I can't really tell what it's supposed to be, but from what I can surmise it's supposed to be a wood texture with splattered glowing paint or glowing dots. Focus on bringing that wood texture to life, and if you see fit to have something glowing on it, make it pieces of broken crystal, or something of the like.

Also, make sure that the alpha-reflections are not as harsh as the preview images make them seem.

Put in some more work on this item and it can really be something magical.

I like the mint-chocolate chip color scheme, and the secondary texture is fun, but I have to really insist upon going back to the drawing board for the main texture. The small images are neat, and cute, but having them tossed onto it in random patterns doesn't flow very well.
