First off the cleric is way too plain. More or less one 'I did something in my pants' look with a few different noses, some new hair and cool green eye color. It's plainly the uglier version of an elf. The facial details are the same scars you can pick from now. I hope there are more things coming because the 'unique' look is fairly unexciting.
Same with the purple knight. A few more faces to pick from, the hair styles seems to be pretty much the same as you can pick now with a few additional 'long hair cuts'. The nose will determine also the facial structure. And some looks are just...a tad on the uncool side. And of course facial details are the same 3 scars you can pick from now. Here's hoping that a few more will be added.
The assassin is better. More facial details to chose from. More scars including a one eyed one, nice. Tattoos. They're okay and covers either both side symmetrically or 1 side only.
The face however is the same with a few nose options, eye options and lips. Nothing different from now. I wish it had several facial structures to pick from instead. The hair styles are all knew - very few and a little on the emo side. Best are of course the piercings. Plenty to choose from.
And finally Bladeforge, by far the most distinguished in style of all of them. Several nice facial structures, addition of blades and the hair styles are raw and 'badarse'. Clearly the most detailed and easiest to individualize of all of them.
I can only hope that there's more to come for the cleric and purple knight. I'm sure with a few more hair styles and better facial details (scars, eye patches etc) the purple knight will be great.
And definitely more to pick from overall for the cleric. It's just to cookie cutter and nothing above and beyond what you can make now.
And perhaps a few more hair styles and facial structures for the assassin. Otherwise all assassins will have the same face but with different tattoos and piercings and that will just be like watching a bunch of emo cousins.
