I have only limited experience with landscape quilts but have to agree with Candace.
Someone mentioned the tree in front of your house being too dark, this can be made lighter with thread embellishment.
I think you will find that once you have added the other tree and the fence, it will come together, and you will be surprised the difference thread embellishment does make.
Don't be hard on yourself, you have had the courage to try this. When I did a course for landscape quilting I found there was a lack of pre course information on fabric selection, so tried to select fabrics with a print that matched the textures in my photo, but I also took to class a whole selection of other fabrics. Once the instructor had explained a little bit more about what we should aim to achieve and showed us samples of her work, it was clear that my original fabric selections were poor choices. I am thinking this may have been the same for you. Even if you are not happy with your end result (and most of the time we are our own worst critic) you have gained the techniques and experience to help master this art if you feel you want to go further with it.
