Thank you! Actually that light was a flash I had pointed outside the door to light up the wood. Come to think of it, I should have gridded the flash so that the spill was minimal. I tried messing with the distortion quite a bit (I'm assuming you're speaking of the distortion on the door frame on the left side of the image). I probably could have done better, but this is why critique exists, a fresh set of eyes to see!
I'm sure he would thank you for the compliment. As for the critique, which shots are you speaking of in regards to paying attention to verticals? The shots w/the kitchen island and rangetop were taken with a 12mm lens and I had corrected/cropped as much as I could without making it look super crazy.
Many times a lens profile will clean that barrel distortion right up, so give that a shot. If you're going to add flash to a tungsten light dominated scene, it needs to be gelled to match the color. Also, don't use a flash if it's not adding any value to the photo.
If you're not already, you should shoot shots like these with brackets that include with and without flash, so you can simply bring in a layer in PS without the offending flash, in this case.
Is that 12mm on FF? If so, that is just so mega-wide and will give you rampant distortion that is not really fixable in post. If you are going to tilt the photo in order to correct the verticals later, know that there is a limit to how much you can tilt the camera and expect decent results after correction. It's the equivalent of using an extreme shift on a T/S lens, which doesn't look great, so should only be used when absolutely necessary.
Not everything in an interior needs to be ultrawide, try some longer focal lengths, so the features you're looking to capture are represented more accurately.
