PE4- Photoshop

So this week I decided to play with photo editing in Photoshop.  I know it's very Elementary, but it's what I could do in a few hours (sad, I know).  This one I drew on graph paper and wanted to cut out the graph paper in the background. I was working with the various vector cutting tools and a friend helped me figure out how to overlap multiple pictures and adjust opacity and also change colors in the pallette.
