Stylistically the visuals we produced had to remain consistent with the look and feel of the TV campaign.
We would be provided with a basic scamp for each illustration, which would have been signed off by the client and agency. Like any other project, we would go through an iterative process for every illustration. We'd work up a rough sketch, then a 3d greyscale and final render, with the odd amend thrown in every now and then! Generally the process was fluid, given the volumes of work produced and the clear and consistent style for characters and assets.
Over 400 illustrations reduced into 2 contact sheets. Quite a body of work!
