Joshua Kaberline:

Simple, but nicely done. I was thinking about doing something similar.

Adrian Petitjean:

Moves way too much. Work the posing. Try working i steps. Check the arcs of the character with the motion trail.

Ryan Woods:

motion and exrpession are good, man feels like hes moving his head way too much, like it weighs nothing (reminds me of the inflatable arm-flailing tube man by my carwash.) suggest considering where the energy originates... does his chest guide his movements? or maybe his power originates from the hips. so when he goes for big sweeping motions you will know what part starts the move first and what parts follow.

Victor Lemée:

lack some weight, camera angle are a bit off. Arm need to be more elegant, take some reference and watch your arc

Gabriel Mira de Assumpção Peixoto:

Some fixes to the movement (mainly the right wrist rotation and make the cycles more distinct) and the lighting.

Alvindra Surya Wardana:

try to looking for more research about conducting movement..

Daniele Croce:

The arms movement are too casual and floaty. Study some conductors videos, it will help.
