Beautiful work - love everything about it especially the backdrop lighting and my only suggestion as a fan of big snakes is that your snake is actually not in a realistic threatening pose because it can't strike far nor could it throw itself at you because it's coiled around the branch. It would need to be more looped over the branch as its upper coil is, so it could throw coils a good distance.
Wow! Stunning! I'm actually looking for a picture of a snake and your's is the 1st one that attracted my attention... It looks really cool and I might even use it!
(Just have to read the terms and conditions again...)
