Modeled and sculpted in Blender with some Texturexyz textures. Used substance painter for the materials and rendered in Cycles.
Very well done, I can see you put a lot of effort in that!
However, there’s one thing that I noticed about the texture, and this is not to discredit you.
The lips look a little too matte, as well a large portion of the front face.
For improving, try working on figuring out what makes a face realistic.
Study references a little more, and focus on the micro details.
Right now, you’re almost there with this face, which is already very good, but I believe you can take it further, you just need to look a little closer.
Hope this helps.
I featured you on BlenderNation, have a great weekend!
You’re on the #featured row!
Great job, I’m impressed with your modeling and texturing skills
