I am glad to see a simple shot from you. (You seem to lean towards busy). I think it needs some sharpening or better focus and perhaps b/w? I love the off center though, good capture.
Interesting idea. I think a tighter crop on the window with the same amount of space to the right might have been a more interesting composition. Maybe even a different light - morning or later in the evening.
This is quite nice. I love the rustic feel of the planks. This would also make a great Black/White photograph. Nice placement of the window. You might gain a bit more detail by adjusting the Highlight/Midtone/Shadow. Nice work - 7
