Very nice. But wait - there's a twig on the snake's head - you should have reached over there and just gently plucked it off with your fingers. Simple, really. On the other hand, you could be like me and just leave it alone. On a serious note, I do very much like the fact that you have chosen a natural subject with a pattern, especially as there are two interesting patterns involved (scales and body form - such a clever title, too). 7.
Excellent focus on the scales. It really shows their texture. Not that I'd want to reach out and touch them though. The little twig infront of the snake's head is a little distracting, but not much one can do about that in the Basic editing rules :-\
I think a tighter crop to eliminate the gravel and the snake's face and a bit darker in the shadow areas of the scales. Also, much greater depth of field is needed so that the pattern really stands out. The foreground is too soft.
