Applying Texture assignment 2: I used a ice cubes image to create a texture for the skateboard. Used liquify, forward warp tool to stretch the image to the skateboards shape. Then lowered the opacity down to 70% and switch the image layer to overlay, which created the rough skateboard texture. I mask out some of the image to show the tiny details on the skateboard, like the drills.  Lastly I used the burn tool to add shading to the ice cube texture to give more a realistic appeal.
