Nice environmental portrait! I would leave it as is because the leaves nicely frame the snake. I would also add a slight vignette to concentrate the eye on the snake even more.
Nice capture Jim, I would crop the tail, the viewer I.M.O would believe it was behind the leaves anyway, and in doing so moves the snake from the center of the frame! but then again, what do I know
I would leave more or less as is Jim with perhaps a small crop from the RHS up to just before the second plant stem from the right plus as Mike suggests, a light vignette. IMHO the knuckle on the tree trunk then become a bit more prominent as a stop to the eye.
I wouldn't have noticed the tail at all, the sharpness of the leaves versus the softness of the snake is what got my attention. I'd leave as is and add more sharpness/contrast to the snake.
+1 to Shadowman
Thanks all for the feedback.
Binnur and John. I did try to add some more contrast to the snake and re-posted it. He was a very light colored snake.
Cropping means cutting that leaf in half; but I would still do it because the main subject is the snake's head. Everything else is 'garnish' or distraction, so it can be trimmed.
Thanks Geoff for the feedback and thanks again John for the suggestion.
