I would definitely not choose the bird on the boat as your lead photo. It tells guests nothing about your listing and why they should click on it rather than others in the area. It's also not in focus. I think that the photo of the exterior of the cottage is much better, or the living room, as your son suggests.
Also, 36 is a lot of photos. I think 20-25 is probably sufficient. You could easily edit these down as several are not in focus (either remove those or replace with in focus shots). Some are really blurry, e.g. the playground, seating area by the pond and racetrack logo (could you possibly replace this with a photo of the actual racetrack?).
I would also retake some of your interior shots with more natural light, e.g. you could open the blinds in the living room to make it seem brighter and fresher. The caption says the furnishings are all new, but I don't get a sense of this from the photo. This applies to the kitchen shots too, but especially the bedroom. Try to take the images with as much natural light flooding in as possible, rather than with blinds and curtains closed and artificial light, which can cast a yellow tone on everything. For the bathroom, I'd be less interested in the shower curtain that the actual bathing facilities, i.e. bath/shower, behind it.
Be conscious of copyright too. I am not sure if all the photos here are yours as a few look like publicity shots. Do you have permission to use these? Should they be credited to the source?
Sorry if I sound overly critical, but I'm a magazine editor so creating imagery or assessing other people's photos is a big part of my job but, more importantly, the images are one of (if not THE most) important things on the listing.
It looks like you have invested in a lot of new stuff for your listing and also that there's a lot of attractions nearby that could be very appealing to guests if presented a bit better. Perhaps you have a friend or know someone who is into photography who might be able to help?
