I think that the design is better than the previous one, but I am a little confused about what is happening around the knee area. I kind of had the same issues when I was modeling my "Oven" Its really hard to get a shape that is smooth and has hard edges at the same time. I just went back to the low poly, and applied beveled edges, around .2-.1 and it really made it look nice! I really like your head!

Btw I mean the hip joint not the knee. oops, the knee looks fine.
