The Monster Hunter games have some pretty interesting armors if you need some more inspiration, however, I feel like what you currently have is very very nice!

Along with light boxes/product boxes, use solid colors around your product. Make use of light in any space you can to make your subject stand out. Try different angles as well. And don't hover too closely or your image may be too blurry and out of focus. Same can happen if you're too far away.

I'm so sorry for your loss

Quit slacking! hahaha jk jk lemme know if there's anything I can do to help you
