The high contrast B&W is really great here. Though, it would be nice to deemphasize the glare off his forehead.
I love the pose and his facial expression. The composition of the photo is good too. I'm glad you got it after he'd started getting out of the tree trunk, else you would have lost his head to the lines of the tree. Good timing
Such a fun image. Its like he is feeling the music. I love the black white. Gives the image a old time Jazz feel.I be proud of this image!To capture a spontanious moment like that is hard. Your did great!
