If you already have crates of drawings, my advice is stick to drawing and stay away from computerized shortcuts which are designed for those who are avoiding hard work -- and there is no other application so centered on drawing skills as TVP. You should also be able to search and find some pretty conclusive threads around here on how to conquer the Wacom tablet. I'd start with "wacom paperless" and go from there.It's just that only now, now I'm planning to actually enter the field, animation apps come into view and I'm not quite sure what I should expect or what I should be looking for. Which app actually rewards hard work --
Paperless animation leads to accelerated speed in production and the joy of discovering a modern approach to handmade animation. If you decide to go this route, you won't need any other application besides TVP, a decent NLE and a basic sound application such as Audacity.
