I would kill for one of your lemon pastels... well okay maybe not a person... possibly just the rodents to feed itGod Lemons as so beautiful.
About the TC's snake:
Yes pastels have it, some higher than others. My pastel's nose fade is actually pretty low, yellows where her heat pits are and browns right above (what do you expect from a 60$ snake about 2 years ago). My normal's brown goes right down to his lips.
Your pastel has fading up to the heat pits, the characteristic fading of the head and neck, and the peach sides. However considering the fact it's already lightly browning, your pastel really isnt the high quality that many buyers look for. So if you intend to breed it, light morphs are your friends (I will be breeding mine to a Lesser), if you just want it to look at, then yes it is still quite an attractive snake, and the morph itself is pretty attractive in general. When it gets older and the dark parts space out you'll notice more fading there, which is enjoyable.
