love the look of it, it would be nice to not have the buildings, or the fence, but you did a good job, you should try using the 'bulge' or whatever filter its called to even exaggerate the fisheye look even more ;), also you could darken the sky a bit here (get a polarizer) :P hehehe, or just fudge it, which wouldnt be too hard here

buildings ?
fence ?

i don't think i see them

Rackham-esque. Gorgeous and clear.
