A few comments. Generally they are nice, but I have a few niggling comments...

These first three juveniles suffer from the same problem. They eye isn't sharp. It doesn't matter how much of the rest of the shot is sharp, if they eye isn't, the photo will look out of focus.

This photo of the dark one is cool, but it has a strange "dropshadow" appearance. Did you process the background somehow to create this?

I like this shot. I wonder if it might be better if you rotate is slightly so that the snake is more horizontal, even if it wasn't really sitting that way.
