excellent game work Kajuma. I’m not a fan of the generous use of black occlusion detail in your diffuse though. I know this is a tendency in game art but it does make it look unnatural.
I think getting some more of the underlying color to bleed through in your occlusion layers will help with this. The uv mirroring is also apparent in the soldiers hair but I suppose it’s not an issue if he’s meant to be viewed with helmet.
I’m curious, why not make a high resolution render of these characters? You’re not contained by game engine in this case. Lovely work.
