Lots of already great suggestions from other Hosts.
Photos
I agree you definitely need to add alot more photos. 25-35 is about right. If you have an amenity, you should have a photo of it. Put captions/descriptions on every photo. Let the photos tell the story of your listing. Many potential guests make a booking decision base on the photos alone. Suggest you also add some of your own photos of popular local attractions,
Cover Photo
Your cover photo is the most important photo for your listing. You are trying to get people to stop scrolling and click on your listing thumbnail. You definitely need a new cover photo. The one you have now was shot in portrait mode (vertical) and Airbnb crops these photos so much of the exterior is missing. It also appears "dark" and uninviting, as if shot on an overcast day. I would definitely get professional photos done. You are trying to convey "warm" and "cozy".
How photo appears on Listing (cropped)

Actual Photo

In the mean time, I would reshoot this same photo with some suggestions:
1. Landscape mode (phone sideways; horizontal not vertical)
2. Clean up the front..looks like leaves or debris left side?
3. Re-take shot at twilight. Open the curtains inside and turn on all the lights. Turn on all available outside lights. Wait until it is just starting to get dark (twilight) and reshoot
Guest Safety
You mention a pond on the property (no photo?), but don't have that listed in your Guest Safety section. I would add that.

Let us know how it goes 😊
