Looks great. Apart from the wing bracing (and this is from my aeromodelling youth, which is some time ago)you might want to think about a bit more fuselage bracing too. After all, there's an engine to go in there (lots of torque), a fuel tank, an RC receiver and a couple (or more) servos. That last lot might not weigh too much, but they'll put a large inertial strain on the airframe in a tight turn.
The centre of gravity (if I remember rightly) should be on the centre line of the wings when the model is fully loaded, so I think it makes sense to have the fuel tank right on that spot.
