This should be an illustration of a cartoonish tiger working on a sewing machine (sewing a tshirt) while an alligator is looking over his shoulder. the backdrop should be inside of a teenagers bedroom. These two are friends just trying to make a tshirt at home. the design would be centered on a shirt probably on a 12x12 space. It's a play on Le Tigre and Lacoste (without having them look like their logos)
below the illustration it should say: "You want to see the inside, I see you later"
the tiger and alligator should not be aggressive looking...
