Second Citadel's comment. This is the way HDR SHOULD be used--to keep detail where it would otherwise be lost, not to make everything look like it's made out of velvet. I gave you a 7. The only thing I didn't like about this photo was that I found the title implausible--I don't think I'd be comfortable sitting in that position for more than about two minutes. Does your daughter actually read books there..?
I personally thought that this was an excellent use for HDR. Normally the background outside would be blown out. In this case you've retained detail out. It would be nice the shadows were a little brighter and the window frame was squared up (darn lens distortion!)
This is the correct way to do a frame within a frame. But is this really HDR? If so it is extremely subtle. But it is better to err on the side of subtle than to go overboard.
