|Hello from Critique Club,
(Composition) Your composition is pretty good. I like the way you have negative space there with rule of thirds... the blue color that covers the top of the image... Idea is good and well executed. I am not sure you were planning to use this photo for this challenge; the tip of the boat is almost touching to the frame of your photo, that's bothering me in this whole picture. It's not bad thing, but it takes a bit attention from overall.
(Technical) Some might think the overexposed area on the bottom a bit lighter than it should, but I don't think so. It looks good too. Seems like two boat attached, or stick each other and hanging in the air via a wooden lifter or something.
(Final) If you had a bit more space between the tip of the boat and the frame, I would say you would be taking it to the "6-land"... I think the over exposed area on your photo and being to close to the frame get your votes a little downwards.
(Personal) I checked your other photos. You seem like in right direction, just need some practice and that's it :)
Keep up the good work
