Gosh! I really love the tidy lines, and the combination with all the colors makes it really interesting. It also follows the golden mean, wich I think is a great plus for the composition. It draws your eyes to one point in the piece, wich makes it pleasant to look at. The person sitting there is also a really cool detail. I love the energy and movement that is almost not even visible, and all the colors. I love how abstract it is. It made me happy to see this, I looked at it a long time. Simply love it.
