I started out with the lineart. I had it black in the beginning but then tried a sepia colour that seemed to blend nicely with the mood I had in mind :)
I started adding colour to the hair
And swirls
Then started shading the hair with lines
I coloured the cloth and added some highlights
I put the base colour for the skin
and then started to shade
I made the wing lineart
then after a long convo with [Teufelsweib] decided to make them teal x)
Shaded the wing a bit
After that [Teufelsweib] suggested using red and with some fiddling around I ended up putting dark red spots on the wings
I added a second wing and then decided to change the cloth colour as well
I started working on the decorative lines
Adding, removing changing colours of the lines etc
Added some clouds to the background
And a darker colour behind the stars but it looked way too much out of place with the yellow background
