Beautiful shots Deeno. I like the extra contrast in the 3rd shot, but they are all good.
Unusual colour to the sky in the exterior shot, have you played with that? I thought initially you might have sepiaed the sky, but it isn't fully desaturated.
When you have the time sit down with PS and you exterior shot and play with the free transform tool in PS. If you want to you can straighten up those verticals with it without too much trouble (on an image like that

), but I don't mind a bit of perspective.
