Old wall alert XD
I spent like... 4-5 hours on the background, I thought my eyes were going to self destruct. It is an old vector from my computer. I forgot were I downloaded it from, but I had to revector it, since the picture was pretty small... 800x600 pixels resolution and after the resize it looked blurry and jagged. The red chair in the right and all the models on columns or walls gave me the headaches. I felt like stopping and grabbing the Smudge Tool to make the background beautiful again... but I didn't...
After all this time working with the background, the girl's hair gave me the creeps... I did my best on her, of course, but I kinda messed up in a couple of places. I'm not going to tell you where!
I hope the 'not that greatly vectored' background isn't in a messy contrast with the high quality and detailed girl.
