That is one super sexy Pastel! For a pet store pickup, I think you got a smashing deal. His blushing is fantastic along his back. Unfortunately, without breeding trials or definite signs of het markers, there is no way to know what Thor could be het for. From what I can see of him (I did look through all the pics, great photography, btw!), he doesn't look like he'd be specifically het for anything. Then again, I am definitely no expert on BP hets and so I could not say for definite sure. Without a doubt, you definitely saved this little guy, because his earliest pic made me cringe. Congrats on a really beautiful guy!
