the rushed high poly pass is really holding this piece back. curved shapes are lumpy. most of your edges were too sharp and went unbaked. components are mostly just intersecting instead of fitting together and selling some kind of functional assembly. for instance, the tube running down the side just terminates at a plate over the cheek instead of operating as part of the respirator. you can only add details in painter up to a point, the high poly needs to get more love
