These right angles are rubbish and inaacurate - doesn't meet the challenge. [1] as there is no zero vote.
Just kidding - I love it! It's a shame the horizon is so tilted though. I would have straightened that and left the window skewed as there is more allowance for the imperfections in the style of the ancient window. [8]
NIce idea, although I find the window just a hint too small. The green grass is also slightly distracting, perhaps if you just got a bit lower down for the shot? Still, it's original and I like it :)
To me the right angles are not the strenght of this photo. I like it very much. I think the composition is very interesting but to me the strenght seems to come from the depth and color and the element of intrigue created in the scene.
I really like your idea here, I am not saying it would be better this way, but would like to see your window off centered a bit more. just an idea. good work.
To me there is too much empty space heere... I think it would have been nice if you had cropped in some on all sides... cool window though. Might have been nice also for inside looking out.
