Did you want constructive feedback from a wanna-be, me?
There seems to be a fold line running verticle on the chest pieces. I'm not sure if there's one in the original, but there is a definite curve in the chest and ab pieces which I think you attempted to replicate.
Otherwise...they look great! The outer angles of the ab piece look really good, the dimensions of the neck piece look good in relation to your chest pieces, and of course your diamond is the best ever!
I'd definitely buy a set!
