When looking at characters doing a 360˚ i found these as a good example as it is used alot in animation, and looks beautiful when done well. The first four gifs are from disney movies, and although the styles seem to change slightly the first two have a similar movement to them with with timing and just the way there body's seem to move around even though the amount of time between each being created is quite a large gap.

With princess jasmine here its nice the way her legs just flow around, looking very graceful and guinea like, with the hair moving with her. Below that we have a cute twirl from the princess and the frog which has a more cute, but less elegant spin.

The first one below is from batman of harly-quinn spinning around repeatedly on tip toes, a very different style of movement compared to the disney ones but also i think that is part of the nature of the program. Below thats is a beautiful studio ghibli spin, which is very fast and a lot simply also then the disney ones above although done in the same way.

I struggled doing a spinning object as keeping the right proportions was seen very difficult for me.
