There was something though i just couldn't put my finger on until i noticed that the window were not totally strait like an image on a moving fabric or trees outside, giving motion that the eye sees but the mind just knows something is happening but not what it is.
Ah. Thank you for pointing that out. I keep being drawn to movement and line, but hadn't consciously recognized that's one thing which appeals to me about this image.
I also like the way you included the wall on the left side though it was smaller it help to balance the window pains.
Too, I think that helps strengthen the suggestion of being in the room and the "reality" that is being reinterpreted by the shadows.
I agree about the large mat but think the narrower mat goes too far maybe something in the middle. The mat did help me contain the space though.
I will give that a try, also keeping in mind Ted's subsequent post...
