This is a pastels eye using a crappy iPhone camera, and you can still somewhat see the green. While I don't see pastel in any of your pics I can't say for sure it's not a low quality pastel. The clear belly and blushing are pastel signs, though these can be on normals too. There are a few things you can do to get better quality pics. Take a few pics outside in the sun. And put something in the photo we all can adjust the color of our screens to, ie a coke can. Once the color of the coke can is matched the color of the snake should be much closer to the actual snake. Hope this helps some.
