Difficult to know what to say about these 3 photos. None of them have any real impact value despite the unusual angles they were taken from. I think perhaps the time of day and the lighting fail to add anything to the photos. Maybe on a brighter day and earlier might work better.
I agree with Tex about the impact. I think the composition isn’t helping either as the bottom 1/3 in all 3 is serving no purpose at all. Sorry. Apart from the trees, #2 is about the best of them. I could be very wrong here… but I wonder if you’re going too wide at 12mm?
I think color wise they are nice but the lower portions of the images are a bit dark, its an interesting subject and one I’m sure if you go back to a few times you’ll get some great images
