Ok so...
1:43, the concept art is great... But the 3d model at 1:52 look really bad, and really nothing like the concept art.
I'd be happy if you were to consider going into materials more like what Danny Mac 3D used to create this 3d model from the concept art of Jessica Madorran
Mainly the glossiness of the lips and general look of materials. The stylization of proportions is a completely different thing, I'm not suggesting a cartoony stylization.
Although, I think an unrealistic, closer to concept art stylization is a better approach than poorly made realistic art. Unless you get something like what unchartered 4 would've been 2018... The realistic approach always end up looking cheap, and ages really poorly.
For example, compare how Borderlands graphics has aged, to fallout... One has a game where characters look alright even today, while the other has really cheap and low quality looking characters.
