Hmmm.... hard to say. I think that both Scourge and Cyclonus look fine in terms of detailing and accuracy, but the proportions in the upper arms and torso seem a bit out of wack. I'm not sure exactly, but the width of the upper torso needs to be rescaled inwards along the x-axis. There may also be some editing of the vertices as well. Well, good luck, shedbandit! It'll be interesting to see how these guys turn out. Not enough Season 3 fan art out there, you know?
Really good modelling and material-ing, but only one thing that seems wrong is jumping out at me... I think it's the angle and the lighting, but Cyc's head and face seems flat. Just throws the top half of the pic out for me... other than that, it's great ^^
