Duel Sided Puzzle Box!!!

I'm a 13 year old boy who recently gotten into 3D modeling. So now this is my first model I'm putting out into the public. It's a really fun puzzle game to play with friends and family, where you have to fit all 8 with in the one side of the puzzle board. Both side are possible. It has a hinge that can have it open a close with a snap fitting things so your pieces don't fall out. Tips are appreciated on what I can improve and the product itself or presenting wise. I hope you enjoy it!!
