Cleaning up the Hind Legs

In the gallop the horse kicks up and out into the air very quickly as it's travelling very fast. To achieve this we'll need to edit the curves of the ankle control's Translate X and Translate Z.

Steepen the curve when the leg is lifting, as the steeper the curve the faster the movement. Then when it's highest in the air start flattening the curve so it'll hold it's pose for a short while, then when it's legs start to fall down steepen the cuve again but in the opposite direction. Your graph editor should look something like the above. Repeat this for the other legs, but not to worry if they're not the exact same as they shouldn't be.

And here's a play blast of what the gallop cycle should look like so far. The legs now move much more smoother than before.
