Very good, but the fisherman seems to have some motion blur. Love the swans - it is anyway a more interesting and engaging composition, made all the more so by the fact that the fisherman is still there. Stunning sky too, and I like the processing.
Edit - I've just had a look at the large size on flikr, and I noticed that there is quite a lot of movement ghosting in the swans. Could you not have taken 1, perhaps 2 of the exposures and then 'created' any further exposures required in the software prior to HDR? I have tried this, and it seems to work when the HDR effect is kept reasonably low, which yours is.
