The dent... yeah, i made it about a quarter inch too big for my tastes, and to look perfect. But for my purposes and Halloween, being my first scratch build, I think it does not look too bad. There are about three things I know I did not do perfect, and will learn from them in the future.
Side note - My brother and I are building a vacuum forming table and will be making armor here after Halloween. If you have something you want built let me know or if you know people that want something, same deal. You can pm me or hit my email - email@example.com
