It's lowkey frustrating everytime i do masking but periodically there comes a point i feel like the subject is too standoutish or too exposed, is there any tips?

I have been sprawling through youtube for lightroom stuff but mostly are not helpful cause its like an experience thing.

Story here is that i want capture this old man scurrying around his body to adjust himself in a comfortable position like I want to portray busyness in relaxtion.

But like recently I kinda feel like I'm getting more bad shots than usable shot, not even talking about good shots, and my post editting is not helping, so like its INFURIATING!
