I agree with your suggestions here. The main photo is currently of the living room and it looks quite crowded. I'd probably skip past a photo like that myself.
The bathroom looks beautiful! I would definitely feature this up the photo list more. Also, many of the photos are too close up. Are you able to take wider-angle photos of the rooms? As a photographer friend says, photographs should include context, not only the thing you want as the focus.
Also, a suggestion from an international perspective: it might be different where you live, but when I see an American flag being flown outside of a house, unfortunately, I wonder whether or not the owner is racist. I am commenting here on the perception, of course! This is not comment on you as a Host. However, I wonder whether this might be putting off some guests.
In Australia I never book accommodation with a flag flying out front for this very reason (the perception here is sadly closer to accurate).
