While Cr0’s coloring is insanely good here: (Like with the red in her hair and how it goes so well with the color of her outfit.)
You shouldn’t sell yourself so short for your sketches.
I’m actually giving the five stars because of the sketch itself.
The rough lineart has a nice flow to it. And things like her beautiful anatomy, use of shapes, and small details, are really well done.
Like for instance, the shape of her legs is very natural and smooth, especially how her feet are posed in her high heels.
Fingers are posed appropriately and looks great at how she’s grabbing her sunglasses.
Even a small detail like using dark lines and a highlight, to show her lipstick, is a very charming small detail.
All of it adds up and brings a lot out in it.
I’d say you did his OC Luanna justice, QueenofShrews! Nice work!
