My snake looks very similar. Go look in my pics on my profile. I consider him pastel. But professionally I can not say for sure. Only snake I have I know for sure of is my pinstripe.
I'd say it's a normal, but with all these subtle morphs we have today, nobody can tell you it's a normal with 100% certainty.
Breeding is the only way to determine what you have, but I'm 99% sure you have a normal.
