Some pic look good, it acknowledges the effort that made this character, but, although it has a good management of photoshop he would need to study further the relationship of proportion of the bodies. Carefully watching some of these images, you can appreciate the inappropriateness of the bodies with respect to the head. (10, 312, 317, 319 for example)
I think all this work should take longer than average, I mean, many for just half a year, my respect for this guy if he is so good is their work, but it would be a pity if it were just pure photoshop.
