Need help with age and score!!!!

I have three different pictures of this nice 8 but all of them are taken with him looking the opposite direction. I love his basket-like rack and tall brow tines but I'm not great at aging bucks. My guess would be that he is 4.5 y/o but I'm not real sure. I would appreciate your help with aging and guessing a score?

Fat neck, sway back, low belly. He's old. Idk how old, but he looks old to me.

Not much to go on but I say 3.5 yrs old and no idea on score without better pic. Belly has too much curve in it to be 4.5+ imo. Good looking deer, though.

He's at least 4.5, if not older.
