The blue is vivid and the frame of the construction is a nice contrast. This would have been great for the "construction" challenge. Although the wood isn't a "natural " frame, I like the picture very much.
I've got to be honest and say I don't enjoy the colors in this image. That is just a matter of personal opinion. Otherwise, the composition and lines are very nice.
Altho this is a photo of a framing of a house IMO I do not think this is what they mean for this particular challenge. I has beautiful blues and it is a very crisp photo I find the photo itself lacks interest/subject. Perhaps a tighter crop would have made for a better photo, for example if you cropped up the bottom stair (about where you see the 5 blue marks on the plywood) and centered the crop (crop some off the right side) would have made for a more appealing photo. All and all I tink its the subject itself that I personally find unappealing. It also appears that the camera was on a bit of an angle giving it an odd depth on the right side of this photo. However I do realy like the blue sky in the background and love the way you have captured the cloud within the frame of the house. Good luck in this challenge. <5>
The color of the sky seems slightly odd. You might want to check the white balance and make sure it's set to outdoor....or perhaps it was just a very sunny day :-) Good clear shot though, lots of detail in the wood grain.
this photo depicts vast knowledge of time and space, using basic structure to send viewer's imagination to "lift up" and wonder, to see what can't be seen through a "window'
