Help me age this WT deer

[GearJunky]

I have a lot to learn about whitetails. This is a buck we have been following for two years now, and we let him live this year. I am curious how old you think he is.

Only photo I got from 2023 -

Photos from 2024 (summer to end of December in order) -

For reference 150” deer I killed in 2023 and he aged out at 5.5 years old.
