Hi there,
You got some great portrait work on here. I like the top image of the male actor. I'm assuming hes an actor.
About your "Great Warrior". The thing that hit me first was the legs. They seem too straight. Legs always have some kind of bowing in them. That's because, the femur bone comes inward at an angle then the tibia goes pretty much straight down from there. So on your "great warrior" do a soft masking of the upper leg. Then invert the mask and with the rotate tool rotate the upper leg in a bit from the hip down.
I hope I didn't just confuse the hell out of you because, I confused myself just now haha
Looking great though, as I said I really like your portrait sculpts. I think your nailing the personalities.
best,
Ryan
