Normally a crested with eyes that sunken in is on the verge of death, usually due to dehydration (it causes the eyes to sink in). But this one doesn't have the wrinkle of skin that is usually around the eye when it sinks in suddenly--it looks like maybe the geckos eyes are deformed or they are like that for some other reason.
I'm wondering if maybe she has MBD or some other severe nutritional deficiency--it looks like she may have a slight underbite as well. Do you know what she was being fed?
Can you post some full body shots? Does her spine seems straight and does she move around okay? How old is she and how much does she weigh? Are her pupils reactive to light and does she appear to have normal vision?
I doubt that is something other then a deformity...The rest of the body looks fine, and the skin doesn't seem like it too loose like it was malnourished. Reminds me of those dogs...what are they called...? Bull terrier!! Cuz of the long face lol
I don't really think she is a hybrid even though she does slightly resemble a sara due to her color and head structure (some of that though is just emphasized by the angle of the photos). She still has crests, and the crested hybrids that I've seen don't have any. And her eyes--just being a hybrid wouldn't cause her eyes to be all sunken in like that. Plus, if she was a hybrid she would have been pretty pricey--unless she is some sort of hybrid project gone wrong that someone wanted to get rid of. I most definitely would NOT breed her regardless, as she has some pretty serious deformity.
