OMG WADDY .. !!
i've never seen this one and its been in your portfolio for over two years ..
its so brilliant .. like an old painting .. the colours, the clouds, the darkness, the lighting .. WOW .. !!!..
its amazing .. :)
This is exactly taken at the right time. Nice warm colors, which aren't whitened out because of the sun being too bright. The boat makes for a nice silhouette against the colors.
However i think this might have been a bit better if you walked more to the left so you could get the brightest sky-area in the same line (vertically speaking) as the boat. This would eliminate the black area, if you moved your point of view a bit more to the left as well. Also this would mean the boat would be at a third in the bottom (as it is now) but also on a third from the right side and that point (third-third) is one of the four strong points in a composition.
At the same time because of the composition i proposed the river would bend into the image from right to left, while now it bends from middle to left, meaning it's shorter path for the viewer to travel out of the image.
Overall a very good idea and you waited for the perfect time. In my opinion a slightly better composition would improve it a bit more.
