This was a job completed at BEanimation.

Work required
The animation was roughed out in house as drawn animation, this was scanned in and would be my guide for recreating the piece in flash.  The backgrounds were laid out in After Effects 3d which allowed me to light the scene and cast shadows.  There were times for example when the character swings his racket that it would of gone through the 3d floor plane so these points needed to be fixed (I used a blank adjustment layer and then the character on top again, the adjustment layer effectively flattens everything even though it is 3d).  There were also some cast shadows that I changed so his feet looked planted to the ground but also looked spaced apart from each other (an example would be at 4seconds).
