Amazing setting and fantastic execution. The calm water, the clouds and the perfect reflection all add up to make this a winner. I'm also enjoying the flying birds in the bg and the distant treeline. Excellent stuff!
There must be very tame (or were you using a blind of some sort?)
I vote to leave the Pelican coming in from the left side in. The reason is, if you remove it,
then you have this empty space on the left and not so much empty space on the right,
kind of throwing the balance off.
Of course you could remove the pelican on the left and crop, but I say no.
