Now click on the layer called Background copy and goto Layer/New Adjustment layer/Brightness and Contrast and set it to Brightness +29 and Contrast +39. Now goto Layer/New Adjustment layer/Black And White and click ok on the menu. Now drag these 2 layers above all other layers. You should have something like the image below.
