I think it’s too simple and there’s a very similar hat already in the chatalog (Green Banded Top Hat). If you keep practicing and working hard you may become the next UGC creator!
I am do not work in the field of 3 dimensional artwork, but I can do tell you that looks amazing, but looks a little too much like the Green Banded Top Hat in the avatar shop. Aside from that, it looks GREAT!
