I would fit a chain gaurd as when I rode a hardtail I found that the chain was constantly being thrown off and you probably do to. I might also fit a single crown fork with slightly less travell as the heavy angle looks very slack with a heavy front end but having never ridden it I don't actually know.
your bike is looking pretty good the way it is, the only thing i would change if it was mine would be to put on a single crown fork... they are lighter, you can do more tricks, and they look so much better. but other than that you have a solid bike.
