Critique - Conductor

I like it much better. The only thing that you need to look out for is the last part where he pulls the sheet towards him. I know it's blocking but don't forget to make it as sad/heart felt/loving/ as possible, so keep the movement more on the slow side.
Same with taking the phone off the ear and down needs to be slow as well, just like the paper pulling closer. You need to see that he gets lost in his own world of music.

And yes, too many poses gives it that cartoony, overacted look, much like Horton (obvious polite but true disclaimer, the animation was beautiful, but there was just too much of it). Less is more with a few well placed accents to give it a nice contrast.

Be careful about the pose change from x50 to 51. It's a big move so don't forget that it will take time to switch between poses. That's why I'm not a big fan of stepped blocking, unless it's like around x200+, where you have more breakdown poses as he sits down. That way you can judge how long a move will take.
