How to crop this photo?

I think it is Ok as is - put it away for a few weeks and look at it afresh.
the sun is in a compositionally strong point and sort of balances the larger
dark mass of the trees to the left. Cropping out the trees will also cut
out the nice cloud shape behind them. The only thing that could be improved
would have been raising the camera a bit so that the boat cover does not
merge with the distant shore line but only a small point.
