Girl in Pink

I'm thinking about what to get for my friend's birthday, a gal that has everything already. I draw this on Illustrator based on a picture of her and a note attached to it. The pink comes from the actual surroundings in the diner she was sitting in, everything in this place is pink! I'm surprised no one painted the plants pink. But playing around with the shades of pink was challenging. I use only 4 shades of pink throughout the piece.
