You look like a classic hardgainer who's done a buttload of work. Very well done man. I'd say chest, abs, back, wheels are good, all proportional for your size. If I were to hit something real hard, I'd work on the arms to balance you out.
Like LS said, I'd ease up on your volume and add some weight to your lifts. I think you'll find that to be a help. And just to add to heavywear, persistence and commitment will be key here. You have an excellent base to work from. The longer you stick with it, the bigger you'll get.
