Alright, I've had a go at making something for Queen Regulita. I ended up going a bit off description, so bare with me here while I explain my vision here.
So, she's supposed to be naturally really sexy, but her outfit itself is pretty modest. So she's got this very long dress, shows off a bit of cleavage and shoulders but still all family friendly on her own. However, the material is so tight that it snugly wraps around her body showing off her curvy body for all to see, and the stretching makes the material is so thin that you can see her body and underwear beneath the material. So you're left with this effect of a tight and partially see through dress.

Her thong here is actually not a true thong, and is just naturally stretched into that shape by her naturally fat ass. She has pasties on instead of a bra, but that's actually pretty normal for Assaheim culture, bras aren't something they wear and this even applies to Regulita.

Originally I gave her brown skin like Cleo, but she literally just looked like Wuya from Xiaolin Showdown. She still does a bit, mostly because of her hair, but with pale grey skin she at least looks more distinct.

As for my other thoughts, I could have maybe made her ass bigger. It's already pretty big though, at least compared to my other art.
Not pictured: Two little guys having to carry her around by her ass.

Let me know your thoughts. If the thread archives before decisions are made I'll repost this in the /aco/ thread for discussion to continue there.
