I think of all your "Mass Age" designs this and Isabella are probably the best of the lot. The only suggestion I would make would be more red. Other than that it's definitely a good decide. The dark blue meshes nicely with her red hair.
Very nice work as always, love the blue pallet! The locust/hurricane inspired mini-SMGs are a nice touch too. Always a bit odd seeing her as a duel-wielder given that I almost always had her as an archer. But then I suppose the ME equivalent would have be a sniper rifle and that wouldn't suit her at all!
I half expected you to draw more from her seeker armored look from the end of DA2, but then I suppose that design will be taken by Cassandra?
I had the multiplayer weapon selection on my tv to get an idea of what to do and settled on the locust/hurricane for inspiration though I didn't even notice they were the only ones with the front grip.
