your shot fits right into the challenge. It just has some minor things to look at. Like the bottom edge is not 'clean' and the glass is dirty on the left hand side. These minor details like these can make an impact on the shot.
The dark bottom and lighter outside scene don't work well for me, seems that if the photo had been taken from the level of the slant this would have been better. Not sure what's in the background a screen maybe that muddles the out of focus area.
