Star Wars Kylo Ren Tie Clasp / Clip

This my first 3D model that I have ever made so I am completely open to criticism. Designed entirely from scratch in TinkerCad so not 100% screen accurate, but it doesnt have to be because its a tie clasp and is pretty small anyways.

Here is the link to my work in progress model on TinkerCad:

Changes:

v2 - Cleaned up some areas, added raised bumps on lower clip bar to grip the shirt
