I agree, with the mask fix, they'll bring it closer to the original art and it'll be cool as hell.
Imho, the only faction that looks off target, for now, is cybertronic. It has too much gothic or grimdark elements.
Chasseurs: they seem ok, though i do hope that the AR3000 rifle will get the appearance it had in its original artwork.
Enhanced (Armored) Chasseurs: These guys show too much tubes and pipes, and not enough "human face". Give it armor plates to cover the internals, at least. Cybertronic would cover such weaknesses. Keep in mind that alot of necrotech shows exactly this kind of "extra tubes". This would perhaps fit for Reavers (units that are designed to secretly fight megacorporation and the brotherhood's light)
Cuirassiers: Too thin to represent attila III units. Those things are supposed to be massive and lift heavy weaponry, so they need hydrolic arms and suitable armor to believe their resilience.
Machinators: These guys are ok, although they look more massive than the attila 3 at the moment, which is a bit wrong.
Everasseur: It looks too cumbersome for cybertronic, and generally has the "dark machine" kind of feel, exactly like the enhanced/armored chasseur, perhaps due to the studs on the armor and tubing.
Immortal: this guy could be metroid? It has too much boobs anyway. There are alot of "wrist-weapons" so far in the new desings.
Eradicator Deathdroid: Spot on, this is the best cybertronic design so far.
