Citadels Revised Edition (2021) Board Game Insert

I recently got the revised edition of citadles (2021) and had trouble finding an insert so decided to make my own. I'm definitely a beginner in terms of designing and modeling so any tips or suggestions on how I can improve this would be much appreciated.

I designed this with card sleeves in mind and the ability to grab the cards easily from the box. I wasn't sure if I should make the card storage something modular that you can pull out from the box but for now I think this should suffice.
