What did you do with his shoulder pose? Is the arm too twisted? That might account for the stretching of the texture. It also appears that the woman has the same problem, although it's not as visible. The shadow around the eye might be because of: a) lashes throw shadow according to the shape of the mesh, not according to the transparency. Wouldn't know how to fix it except by turning the shadow completely off for the lashes. b) judging by the position of light on the left, it might be some weird refraction of the apple of the eye. Tried higher render settings? Or the light is too close? Well captured expressions and pose, btw.
