Hi Eddy
in my opinion, I am not sure if it possible to get any huge improvements.
reason? it is a very busy photo, and with all those branches hanging over it they all draw attention on there own.... like a big competition for your eyes.
possibly a different time of year like the fall?
possibly cropping in on just the front nose of the boat with different lighting and things in bloom?
what does it look like when you are further away and the boat is smaller in the frame?
I am not expert, that is for sure...
good luck with it!
will be interesting to see other opinions
cheers
