HBU – Enhanced human units with a blue color scheme.

Angels look good. Monks have too much contrast, so either the upper clothing should be darker or the lower clothing should be lighter. Knights also need some improvement. You should add a pattern to the shield and patterns to the clothing.

I don't think they have that much contrast; rather, it all depends on the lighting, which can be seen, for example, in the screenshots with the angel. As for the cavalry, it's unlikely they will have patterns, except for what I've already added to the flag on the spear.

Dear footmen, what will you be doing after the humans (hopefully, units from other cities in the beta)?

I'll probably work on something else. Besides, I'm not familiar with the beta versions of other factions (I only know Haven from the alpha, beta, and final versions). I only know that Inferno hasn't changed much since the alpha version; only the textures of the demoness and cave lords were changed once).
