WOW man, this one looks great. I find the lighs and shadows much better looking in this one. Also the skin. The feet give me a strange feeling though, i dont know whats wrong with them.
The other studies are also amazing. One thing i found is that in the kid with sword. The sword seems big, but it does not tilt towards the tip. Even if the kid is incredibly strong (or the sword is plastic), i think it should tilt a bit downwards in the tip.
Overall great work. I envy your speed man.
