I love making handdrawn animation, in any semblance of visual style from Chuck Jones-style Looney Tunes to fully anime with lots of splendid detail. When I make animation I go through these phases:
1) Discussing art style with the client
2) Designing characters
3) Devising script
4) Devising a storyboard
5) Devisisng an animatic
6) Illustrating background art
7) Outlining keyframes
8) Outlining tweens
9) Colouring
10) Shading
11) Special effects
In doing so I try to be as meticulous as possible given the time and the budget, while some of these steps may also be skipped entirely, depending on the style of the project and the level of detail. Whatever you have in mind I'll be sure to bring into life and make a reality!
