I can't say that I am very fond of photos of parts of doors, etc. I can see the point however. The mirrored door reflects the lintel in a silvery way, which adds some spice to this.
Hm, I see more angles than parallels, and the parallels are only if I try and find them. A tighter crop to the door and frame would help, as would a boost of contrast to make the white walls white. To prevent the yellowish coloring try and use the white balance controls on your camera, the indoor setting should overcome the yellowing effect.
