That looks NOTHING like like a lemon pastel IMHO. It looks like a very low grade pastel to me, fine for a pet, but one I would pass on for breeding stock.
IMO usually the enchi's that i see exibit a red tone to the blushing that is on the top of the snake. I do think it is a nice banded pastel. Might give you something different in breeding.
