I don't know where this one came from, but i had this background i did a couple of months ago.
i sketched a face on in chalk then painted the outline in gesso. then i used a sponge to apply the next layer of paint.
i forgot to take a pic of when i sketched the angel on but i this is at the stage where she didn't have a face yet...
I didn't really like the way she looked at this stage so i changed her clothes and hair colour
the finished product
Edit: the second stage photo i digitally edited on photobucket and used it in a background of my own creation at pimp-my-profile.com
