I created Robot High school in about 4 hours. I started with a sketch on paper, scanned it into Photoshop CS6, then did the official line work on the first layer. The next layer was the base colors, after that was the shading and shadows layer. Next was the highlight layer and another layer for polish. Then finally was the background layer. I used a few robot references to create the characters. For some reason unbeknownst to me I kept imagining Dexter's laboratory while creating this. So I guess in a sense you can call that the inspiration, lol.
