This is a fabulous shot!! The thumbnail doesn't really show what to expect. With this framing at 10.5mm, I guess you were only inches from that snake. The lighting is well balanced, it's a great shot of the snake in motion, and it's lovely with the view of tree and sky above.
(And suddenly I'm reminded of one time at Wakatobi, when I was framing a shot of a nudi on a reef wall and a snake suddenly swam from below, up between my facemask and the camera. Gave me bit of a surprise ...)
