Offering a snake for sale as a particular morph, because it looks like said morph is dishonest and unethical. I think a seller should know the genetics of a snake they are selling, and truthfully and simply state what the facts are.
I personally only deal with Black pastels and I prefer them to cinnis. That being said there are some stunning cinni combos out there (yes yours Brandon) but I would be vvvvveeeerrrryyyy angry if someone tried to sell me a cinni as a Black pastel simply because it looked more like a Black Pastel. However I wouldn't buy a cinni looking Black pastel and I wouldn't buy a BP looking cinni if I were into them. This is one morph that I am even more particular about getting exactly what I want, and what I want in a BP is deep blacks, more orange then brown in pattern, and most importantly lots of pattern blending tweaking and shifting. The draw to me is more the pattern mutation and color comes second. I love how my Black Pewterblast has a washed look, but you can make out a connect the dot looking blended pattern of a Black Pastel. His mother has more patterns blurred or blended together then not, and is almost the perfect example of what a Black pastel should look like. I can never get pics to work here so if you want to see them check out KandK_Pythons on Facebook.
I guess that photo is a cinni and in my opinion a poor-mid level example (the only redeaming factor is the almost near perfect pattern color for a cinni). If I am wrong then it is a veryyyyyyyy low grade BP and one I wouldn't even consider buying.
