f*cking dope! If I were you I'd re-shoot it slightly more exposed and maybe more of a 2:1 crop with the rider over to one side. Thats just my 2 cents Gets me stoked to go fire off some more 35mm!
The green looks good for sure but I think if he wasn't wearing a white tee the shot would seem very noticeably underexposed! I'd just like to see him pop out a little more without spoiling the natural light
