I really like this image. I'm wondering if you noticed how the line of clouds with the blue below almost line up with the waterline of the boat when you were setting this one up. I see the lighted area that Ursula mentioned as well. That helps a lot to light the details to see in the boat.
There is quite a lot of woodcrafting art to building this kind of boat.
Beautiful composition, interesting light though, did you use some sort of lighting on the underside of the boat? There's a shadow there, but it looks like it's lit up, especially the red. Sort of like a shadowless day with lots of sun. Very curious.
