6. Open up the hair PSD as a separate document in Gimp. Pick the magic wand tool and select one of the designs. Get the gradient tool. Pick a bright color, such as bright red, for the foreground color. Make white the background color. Use the gradient tool on the selection. Select > Deselect. Get the lasso tool and make a selection around the design. Copy it and paste it into a new layer in your snowboarder image. Rotate and reposition it behind your snowboarder as desired. Continue doing this with other hair image. Experiment with layer order, size, rotation, colors, etc.
15. Click the grunge tool. Now go crazy with your brushes. Be sure to change them by scaling them, changing opacity, etc. You can even use the Dodge/Burn tool to create a neat effect. In the end, you should have something similar to mine. There you go. A neat little grunge-style poster.
