Hi,
I've been breeding reptiles for more than 20 years and have hatched over 100 species, I know quite a bit about the markets now and over time.
There isn't another reptile I can think of where pictures of the parents are less relevant than GTP's. You are never going to see anything like the "little clones" phenonenon you often see in clutches of other pythons. This is pretty ironic becasue so many breeders are so proud of their parent pics....which IMO are almost ( i said almost) decpetive becasue no matter how many times you tell prospectvie buyers they believe they have a "good" chnace of their animal looking like a parent, they don't.
There isn't an agreed upon "beauty" standard in GTP's that correaltes to price either - more unusual animals are coveted and priced accordingly but generally speking you won't get a group of GTP folks to agree on whihc one is the "perfect" (aka high dollar) animal - like most reptiles where very little is understood about heritable visual characteristics the premium is on anything weird and anything slightly reliable (like some of the yellow/blue bloodline work). It is important to remember that with an average 5-6 year birht to breed cycle and the first ever captive breeding relaitively late - that combo means that on a practical basis means what is known now is much less than what you'd reasonably expect.
If you have knowledge of other reptiles and look to make snese of the GTP market and pricing - good luck. LOL
All the best,
Ross
