Qui Gon is still looking like a draft to me. Maybe add a little more contrast. He had more wrinkles and the area around the eyes could be a little darker. His beard is still very brown, he had a few more white hairs I guess.
Not bad as a young Liam skin though :P
Obi Wan on the other hand came out pretty well.The hairline also seems a little rough. His eyebrows might a little too blurry. Don't forget to add the birthmark on his right cheek, if the Mesh UV allows it.
