To me, the sky looks a little pixelated which could just be my monitor. I really like your photo, the reflection is great and doesn't overpower the boat. 9
This shot could exist with or without the boat, making it very unique to me. Sometimes when I look at it, I see the landscape first, sometimes the boat is seen first.
Wow, lots of potential in this shot. Dead center horizon does not work for me here. Maybe crop the bottem third to emphasze the trees. Or crop the top third and empasize the reflection.
I dragging the line a boating term? I dont know what it means and the image doesn't really show me. You did pretty well for what looks to be some harsh challenging light.
