Need more pictures and as QBD2 said that's a on the hoof decision. If I felt like he was only 3.5-4.5, on a farm i thought he had a good chance to survive and was getting pictures of him regularly I would likely let him walk. Taking nothing away from the deer, but the picture you posted makes them look about as big as they ever could just by the angles. That deer is likely low 130's maybe.
Depends on a lot.....any one else hunting him, seen him, think he hanging close by or just passing thru, do you want another 130 deer or 140 and up, will you be disappointed when you put your hands on him and he not as big as you thought....that is the one question that only you can answer. Nice deer but would not last long if in heavy pressure area.
If it was somewhere he might make it I'd pass and next season he'd be a freaking MONSTER. But cars, your buddy on the next property over , and a host of other "maybes" might rule that out.
