Well, to be honest, here's my critique:
1) The chest armor is all wrong for Boba - too many straight lines
2) The shoulder bells are way too narrow.
3) Not a bad back piece but a little too rounded overall.
3) Collar plate is too skinny.
4) Pretty good on the dents- gotta admit that.
Not sure what this guy charges. I've made over 50 sets of Fett armor for here as well as on Ebay. Here's a few pics of my work:
My Jodo Kast version (essentially the same as Boba except for paint and damage)
and here's my custom (again with Boba chest armor but with the addition of Jango style legs)
Note: These are based on the WoL templates so all design credit goes to him.
And just for fun, here's custom back armor I made:
