Ốp lưng iPhone 12 Pro 2 mảnh

I created this case to print in two separate pieces for use with harder materials. I printed using .4mm nozzle and .15 layer height. I used organic supports which were a bit tricky to remove from the overhang on the bottom half. The friction fit seems to be doing it's job well. This was my first design so any suggestions on how to improve are more than appreciated. 

Added v2 that has a better locking mechanism for top and bottom half
