Your snake is very pretty, however pics with better lighting would be great, some pics he looks pastel, some he looks normal.
The pastel gene does not work that way, not to get too into genetics but the pastel morph is a co-dominate morph meaning that any normal offspring produced are just that, normal. They are not het for pastel.If you breed a normal to a normal you will only get normals, no matter what co-dom morph one of the parents are. The term het only applies to recessive genes such as albino, lavender, pied, clown etc.
A pastel x pastel pairing will give you,
25% super pastels
25% pastel
50% normal
I think
But the is a very pretty snake
