been doing some of those animation workouts that ian suggested. got about 6 at the moment. several of them still need tweaking. here's what i have got so far, feel free to comment, although if you post negative comments i will come to your house and force you to listen to an Olivier Newton John album.
Here is one ive been working on for some hours now. reletively pleased with it, im sure it could do with some improvement.
and some more.
