Basically:
Bulky =/= fantasy
Most gripes are not about the style but the size of the style (which I agree wholeheartedly on some of the weapons), that bow looks like it shouldn't be able to be lifted its so big. As far as looks go, well just look at Ifrit, look at a dead Ifrit, then look at those weapons...
We killed him and used his body to make those weapons if you still aren't getting the idea I'm trying to place in your heads
The art makes total sense, the player to weapon proportions however, do not.
