A lot of things really, I just wanted FNaF themed nsfw models with actual robot characteristics, my main refs were deus ex (in terms of augmentations), works of carmessi, quotethefox and jaeh.
Using Deus ex as refs for augs and bio-mechanical limbs makes sense, when it comes to other models they tend to be more "fleshy" looking, yours is (in my opinion) one of the better ones that have a perfect mix of mechanical and organic look
