He really seems to be missing that super pastel extra white and blushing typical of most super pastels. Is that what the seller sold him to you as? He is a good looking animal but the super pastel I would question.
I can see pastel .... Super pastel .. well that could be iffy. It is possible, as not ALL super pastels have the bright yellow and super blushing but the majority do. If he was produced from a super pastel x super pastel pairing then he for sure is. If he was from any other pastel x pastel pairing then it's a guess that he is a super. While he is a beautiful snake with a nice clean pattern, if he is a super, he is a low quality super and should have been priced accordingly. Hopefully you did not pay average super pastel pricing.
