I wish there were a bigger lineup of non-binary models, as others have stated, and though I like that there are disabled models, I found it a bit odd that all of them, or all of the ones I've seen at least, are only non-binary.
Also, I wish there were more expressive face references, or just more in general. Most of the ones I've seen are from the same few models with not as much difference between them as I'd hope, and a lot of them are in very similar angles and lighting. I also wish there were more diversity in headwear, hairstyles, race, etc....
