Well I hope Suika Sohma and akirayuna san are still accepting entries...
It's a slighty different version of my design of Ayumu, in which she has a sleeping mind in her hand.
Basically I added some wings, which I didn't add in the rough draft because I wanted to depict them more like shadows, plus I put a tatoo on her right shoulder.
Done with painter
line art: smooth round ink
coloring: various airbrushes, blenders, and some special effects(pixie dust)
Amount of time: no idea
Hope you enjoy it!
