It's far from the best Bryar model... it needs a lot of work. Not to mention, the source of the model's references are not cannon, and thus, the reason I didn't use it when doing my Bryar. It still looks nice, but the lack of perportions, lumpy barrel, and too-angular curve really don't say "best ever" to me. Whatever program you use [if it's jed.... nevermind :-P ] you should use your reference shots as a background, that'll fix all of your perportion issues. As far as lumps go... don't just push pieces together and trick the model into looking like your reference does. Actually build the many parts you see on your reference sketch so that it looks like the reference because it IS the reference.
It's certainly your best work, just not THE best work. Keep at it.
