Though unable to produce any meaningful work, I was able to timetable my next five weeks. Roughly there's still 3 weeks of CG time left (which includes some spillover). With about 2 and a half minutes complete, and quite a bit of reasonably easy content left to produce, I'm feeling fairly confident.
In truth (and not to take a defeatist attitude) I understand that there are other deadlines further down the road, and it's my goal to make the CG absolutely sing and use to 2D sequences to round off and totalise the overall experience in time for the May 27th deadline, even if the animation isn't quite resolved for this time.
Next task (to get back into the swing of things with Maya) is to resolve a couple of sequences that I left on the cusp on completion before Easter.
