I recently created a fake game app screenshot to show my skills at level design. This screenshot was created using both Illustrator and Photoshop. I based the style of the character on the iOS game Megarun.
This is a test sample of a children's book I want to create at some point in my life. I may do some more experimenting by adding textures or styling the background more, but for now I wanted a rough image of what a page could look like.
