Hi all, appreciate if you can help me spot for any anatomy errors here, its easier to change at this stage.

oh ! anyway, more of this piece, i'm thinking of featuring Aaron the Military fitness instructor teaching the soldiers  a balanced healthy diet. There will be a food pyramid drawn on the board behind. The back ground would be an army traning shed. behind the whiteboard would be some wild grassy place.

the white board will be very old, mossy and dirty.
