hmmm I think it would have been a good idea to discuss these models here in the forum during the creation process... the models do look nice, but somehow they are quite similar to each other (except for the electro). Might be difficult to identify properly from a distance.
To me, the shotgun should be somewhat slimmer, though I do like the approach. But I think it shouldn't be such a heavy-looking, huge blaster-like thing.
The hagar reminds me a lot of the UT rocket launcher...
Maybe if the shoulder thingy gets removed from some of these weapons, they would already be more distinguishable?
All in all they look quite professional and well-crafted. I am sure people learn to tell which is which even from a distance with a little practice.
EDIT: Aww forget it. Just have been looking at them again and I actually like them all. Nice job!
