I can imagine this was rather less than easy to photograph Stuart. Getting what may regarded as an ideal pose would I imagine take some considerable skill time knowledge and patience. I like the colours in the snake and the eyes and nostrils are sharp I find the image a little awkward to interpret accurately I can't work out if the pink areas are undersides of the snake or it is actually coiled around something.
The background is slightly uneven in colouration I suspect this is due to processing rather than actuality because it is very delineated. (??)
I hope this doesn't sound too negative because I do find it a very interesting image.
BTW how big is this snake??
Colour palette here is so striking and you have detail in the critical area around the eye and head. I'm trying to figure out what the snake is wrapped around - presumably part of a plant. Background is great and really helps this one pop. A very punchy image.
