Well the representation of orcs and elves in Might & Magic games is a little off from what the modern fantasy have settled. So the algorithm is having trouble recreating them closely resembling, especially since I am allowing it to deviate a bit to get prettier results. Like for example the "elf eyebrows" seem to be quite uncommon in modern fantasy, hence they are missing here.
I have no idea to what extend the resulting inconsistencies will be fixed yet. The only sane way to do that would be to just manually paint over the current results. As for now I prioritize coverage over consistency with the original, because there's a lot to argue about which will just stall the development forever.
I've noticed the devs were painting over the eyes with some bright color, if you were to zoom in the original portraits it's very noticeable. I didn't do that, but maybe it is necessary. I think the eyes get lost after scaling down the images. Also many female variants use lots of makeup, so that blends the eyes further.
Edit:
Btw regarding the orcs, when I was doing the npcs, the results with the default settings where the algorithm tries to stay close to the source were producing crazy bad results, especially with them. The algorithm just didn't understand what it is looking at, so I had to crank up the settings and allow it to deviate a lot, so that we can get nice looking orcs. I did not do that for the player character orcs, hence maybe you are seeing similar results, imo they are not that bad, but maybe throwing away the originals here as well may be a proper direction. It's not too late for them, so got to experiment some, we'll see
