In theory, I like the rationale for the darkspawn looking different- they look more like they're supposed to be humans, qunari, dwarves or elves affected by the Taint. So having them maybe look a bit more like their original race is fine. But the hurlocks look too much like humans with bad psoriasis or something- they're not scary or menacing looking at all looks wise. They look like your dime a dozen zombies you find in every single game nowadays. They don't look mutated enough- the darkspawn are supposed to have blighted, nasty skin while these guys are pasty white and hop around like the flying monkeys from the Wizard of Oz.
And in theory, having scrapped together armor is fine, but the execution is so uniform and uninspired looking its like they're all Total Ware clone soldiers. They say the darkspawn looked too Tolkien orc-like in Origins, well the armor in DA2 for the darkspawn looks directly like stuff taken from Peter Jackson's LotR.
Its all subjective to be sure, but I don't see how this is any improvement over Origins. It all looks more generic and "meh" inducing.
Skeletor doesn't even like it:
