Hair is really difficult for me, Yours looks great.One day i should play with it more, can't get all those cool plugin$ though so might be really rough for me but i can live through it for now through your work. Character looks great.Did you try a detail map (idk if that is used for characters) but a pattern to place over the leather? Its what i'd try, idk i feel some clothing details should be noticeable. Looks like the fabric pattern for jeans and such and doesn't sit well with me being the viewer not expecting to see that pattern on leather.Probably a different vein type pattern for the leather with some good, cracks in it so try this.Add the vein ^ to the normal map you made for that leather work, then go back into substance and "rebake" some of the maps and try to get like the curves/cavities and such to shine through the leather work, that might add a lot, hopefully you get what i mean. You basically have to make a "custom" situation for that leather work.Best of luck, thanks for the like.
