Ripped Paper Creation In Photoshop

In today's lesson, I decide to change the background of the "CHART HEAT" into a piece of ripped paper, in order to make it attractive. So I found a image from Google, and use Magnetic Lasso Tool to crop around the edge of the paper. I order to make it appeal to my colour scheme, I change it into blue colour, which is as same as the colour of skyline, which creates the house style of my magazine. I also create shadow around it by adding effects. Therefore, the chart heat can stand out more.
