Wow!!! this is your work before training???.. they are FAB!
To critique them honestly, the smiles are a little inconsistant and they are a bit wide at the sides (nothing that can't be fixed with a little tweaking)
Some of them look a little rough at the free edge and a quick file would sort that..... but apart from that, if I could knock out a set like that when I started, I'd be thrilled with myself and all I can say is, I'm sooooo looking forward to the pics you post when you have qualifed......
WELL DONE XXX
