Do you have pictures? When does a snake that's IMG start showing signs of it? I swear my female's getting darker every shed lately but I've been blaming it on her increasing age. I could just be imagining things 
However, if you DO have any pictures (especially over time) that would be pretty awesome. Clear up the debate so we know what's what, eh?
