THis is awesome and the bottle looks great with all the subtle colors!!!!Do you know if this contest is opened to non digital work? I've been asking around but get a lot of different answers. I just wanted to know what dimension I should measure my paper to before I start drawing on it.
I think that's all covered in the official rules. You want it to be at least 300 dpi and a 4:3 ratio. So something like 20:15 would work, with 20 being the horizontal length. I'm not sure what you mean by 'non' digital. Whatever it is you still have to give it to them in a digital format. So if it's a photo of a sculpture -- you could use that but they're not going to to judge you purely by the sculpture. It's the overall design that's important and how it reinforces the question "How do you drink Dr.Pepper"
