It's a describtion for sexiness. I painted the picture just for fun and also to add a picture to my personal work list.

I designed the succubus in very general form with pale skin to create a gothic mood and puted in general background which is a desolate place seems like the hell.

I intentionally painted her face very calm to make a graceful appearance for the character. I believe sexiness of character is came from her or his pose, exposure, bold and grace.

After painting, I realized the character face is quite cute in some way there is no much(..) intention on it.

I hope you like the picture
