Just and opinion: there's quite a bit of difference between the upper half and bottom because the cheeks(esp the left cheek) and thighs are pretty blur and smooth (used a lot of the blur tool ya...?) whilst the calves and feet aren't(there's quite a bit of texture on the calves) and the lighting is very soft on the upperhalf too, unlike the bottom part of the legs. also... isn't the transition from the legs or rather, buttocks to the stick and vice versa quite sudden? why not try to make them blend together slowly. perhaps the buttocks could have a little woody texture? =/ in anyway, still looks cool xD
