Shot my first RE shoot with my newly acquired 6D+17-40. I do kind of notice the loss of 1mm coming from the 10-22 but I feel like this lens looks more natural at 17mm vs the 10-22 at 10mm.

Good job straightening the lines. Just a thought - have you considered cloning out the sun spots on the floor in the foreground and at the foot of the corner lamp? Seems like a small stain behind the couch too. Just slight distractions to my eye and it seems that window blinds always will do that! Great photo either way
