I too am a sucker for ze robots in scarves. But that isn't the only reason I really, really like this picture. First, we get to see Red's rare smiles. Very seldom do people draw him happy or serene. Secondly, I like the proportions. Nice broad torso and solid arms. The head could stand to be a little smaller. But altogether, a very solid pose.
He looks fantastic! I love the pose and the expression on his face is just too perfect and to lovely. Maybe he's just managed to get out for himself for a while and spend some quality time away from all the hectic life around the Ark. The movement of the scarf is wonderful and I love how you have handled the shading in the white sections of both his armor and the drapery of the scarf itself. The blue in the background is just the perfect color to make him pop as well as the hints that you capture throughout the rest of the drawing. I love his hands! I have such a hard time with hands...really needs to practice more... Much <3 here for Red!
I wanted to do a happy Red for once. These characters are all get stereotyped a little, but they do have different moods -- even Red. So I thought I'd give him a chance to be at peace for a moment. I think it suits him.
