Well, this design combine a traced photo with the bitmap image.
First, I've traced the girl's photo on Illustrator. Then the vector graphic was copied to Photoshop as pixel object. On the next step, you just need to add some cool ornaments to compile the design.
Here, I also added some of my hand drawing design that I've posted before. Simply I select some part of the hand drawing design the paste it on the canvas. Don't forget to set the blending option to be "Multiply". It will get a better look.
So, that's all. Pretty simple, no need much time to design it. Just select, copy and paste, then make a good layout on them....
