hey nice trousers! Are all folds from marvelous? I know it's probably too late to change the sculpt but I think that face area compared to skull is too small also nostrils seem to be too flat.
Maybe you should check his face proportion/relations again , all of his face features are bunch up like in asian face and appear flat also please fix his skull he has box for a forehead , you could also add him a proper zygomatic arch…
