Level 99 Games - Sakura Arms insert

I am new to 3d designing and this is my first project. I wasn't able to find any 3d designs related to Sakura Arms, wanting to find an insert for it. So I tried making an insert and I'm happy and proud how it turned out. Little lid lift.
(This was designed for Level 99 Games' Sakura Arms. It may not fit in other versions.) 

-There's 18 deck boxes, one for each Goddess. They should fit up to dragon shield (120 microns). However, it may not be able to additionally hold the Alternate versions. The other Goddess' from Bakafire Party will not all fit into the one box, a second box will be required to store the the extra Goddess'.

-A container for the side board pieces. 

-A container with a slide lid for all the sakura tokens and other components. (this one could've and a better snap hold)

Please tell me what you think of it and I welcome you to improve this design.

Thank you.
