A Better Background creating process

It feels as though my processes in with I create backgrounds for my animation is inefficient but it’s the only way I know.

First, I fully animate the character( s ) in the scene with vaguely sketched backgrounds. Once I’m done with that, I export all frames with camera angle changes and import them to Autodesk Sketchbook. From there, I finish the backgrounds, then I reinsert the finished backgrounds to their ideal frames.

The reason I use Sketchbook is because the perspective tools and my cintique and handle it better than Photoshop.
