This is a pose in a personal test animation I did. In this pose he is taking a stand and saying, "I'm not gonna do that anymore." In response to people telling him what he can and can't do in life.
Added a background image to support the mood and create lines of interest to point back to the character. I also reframed the camera to set the character over more screen right.
Added lighting to match a campfire setting. I beefed up the character's arms, and slightly adjusted the pose.
I did a complete pose overhaul to better sell the attitude of the character. I reframed the camera to get more of a profile angle of the character. I actually did some slight modeling to the character's pectoral area where it meets up with the arms to get better shapes there. I shortened the character's chin and did an overall proportion adjustment on the chest, arms, neck, and head to get a more appealing pose.
I blurred the background to give some depth of field to the shot, and adjusted the pose slightly as changes in animation demanded.
Pushed the lighting and the expression a little more.
With some help from Skirsch Kirsch, here's another lighting pass.
