Body mechanics (animations)

I had much more problems with animating the throwing character than I expected;
some things in all three videos, especially the issues with timing/spacing, still need to be fixed, but I had to move on to the next exercise for now

Body mechanics exercises- sketches

rough key poses for three animation exercises- throwing, hitting and jumping- animated later;
when sketching, I found the jumping sequence the most difficult to key, actually, while other two turned out quite satisfying
