Everyone is going to have their own preferences at the end, which is totally fine since you're allowed to like what you like (so as long as it's legal), so it's kinda moot to argue about it.
Personally, I'm glad that Nyl does character models of varying body types. Aside from it actually fitting within the D&D universe, I'm generally open/actively into what he's put out. So if the girl has a bit of a gut, cellulite, smaller tits, more muscular, etc. It's fine by me. As long as he never puts anything out that's just overtly BBW, it'd be pretty hard for him to miss imo
There's also a reason why so many 3d artist use his models, so even if you personally aren't into them (which, again, is fine) you can't argue the quality of his models.
