Tbh the model isn't done yet neither. You really need to take more time into lowering details the player won't see. This counts for both your model and your UV map. This is an old game
Small details in PR need to be much more simplistic then you have it. PR doesn't require all cylinder shapes to be that round neither.
As for your UV, only UV when your model is 100% done please, and it isn't.
the UV is not good at all tbh, take some more time watching videos about making good UV layouts. A texture artist is going to have a rough time texturing that. There is need for much more welded faces in the UV. Way too much wasted texture space and as KaB says detail in front of the player should always receive the most UV space.
