nice, but then again like the other guy said, people have used these designs before which makes it hard to come up with a new design, I really like the tiles on the head though, as for giving cred to scorp for more than arms, well, who knows who's creations scorp might have looked at to make his you know? As far as I can tell from scorp, he's great at decals, but alot of his creations that are original aren't very good, and the others he admits to basing off of someone else, so really you can't credit scorp for very much at all anyways.
This is a great brute chieftain, but this doesnt seem very original. You used the droid arm bodies which Scorp came up with, and elements of his design appear in other parts of your brute (the only thing that looks original is the legs). I love this chieftain, but I think you should just give a bit of credit to Scorp for coming up with this stuff.
ooh, nice! ugh, I'd hate to go up against THAT guy, no matter HOW many plasma rifles, spikers, carbines, and rocket launchers are in the pile under me. perhaps if I had a few Grizzlies to back me up I might. perhaps my only suggestion would be to do a little Sharpie work to fit in some of the smaller details, like the silver-y lining on his armor and his face.
