When is it really done? Well in truth, there's a point where you know you're out of time and you decide to make the best of what you've got, rather than beat yourself to finish your original idea. This usually happens to me two weeks before a deadline. I stop working toward the original description and I coldly assess what I have with a fresh eye to taking what I have and figuring out how to best show it off.

This is a general guideline and doesn't apply much to a single frame (and even less to a reproduction of an existing image) but the structure can still be the difference between finishing or not.

Note: It's finished when time is up. You're better off to have the entire work to show in development than one element that you've spent time on. In the film (and video) world, they're paying for the frames, not the elements that make them up. If you're short on frames, your contract gets you sued into nonexistence and the fight is over. Frame quality is subjective - if the client doesn't like the frames - you're asked to redo them and the fight continues...

This is where the final image will be (this is the original).
