I like that it's even, but it sounds too laboured. Put some spring in the step, rhythmically. Why is the LH trill so bad? The RH trill was pretty good! Brush your teeth with your LH for a while.

I can throw much farther with my right than my left, but I can still throw quite far with my left. The footwork is an important and difficult aspect of it. How is your juggling?
