Ok, this one follows the rule of thirds (as close as I could in a first try). It looks good to me, but on the other side there is so much “empty space” at the right side. That would not happen if the figure was in the middle. What do you think?
This is my favourite so far. If you don’t like the empty space, do something subtle there, something that will draw your eye to the character or contrast with the character either through light/shadow, pose or color. Some ideas: cast the figure’s shadow across the empty space, add a painting, plant, window or statue. If you give the statue a subtle tone that blends well with the background, it won’t distract from the character but then you can play with a subtle message in the statue’s pose.
Just some ideas to work with.
