I remember a post very very similar to yours last year, same kind of subject... silhouettes of blobs and bundles of sticks in trees (except for #1). What is it that you experienced on your walk that you want us to see? And remember, while you were there, we cannot hear the ambient sounds, the dog barking several blocks away, the crickets, the gravel or grass crunching under your feet. We cannot feel the crisp night air flowing across your cheeks. We can't smell the burning firewood or fresh pot roast that the neighbor pulled out of the oven. So it seems that your images may have some connection to you that cannot be transmitted to us.
I do not know what you are trying to communicate with these, except for #1. When i look at #1, I might be able to create those other sounds, smells, and feelings, even emotional feelings, to the image, because it's a traditional icon of fall. The colorful leaves about to fall from the tree.
I think you could have made a greater impact by filling more of the frame with the subject leaves and making sure that each part is separated from the background by placing it against the sky in the background. The camera needs to move down a few more inches for this to happen. And as TCD mentioned, the leaves are quite underexposed. The problem is if you correct this, the sky will then be overexposed. Maybe a polarizer would have helped, maybe not. Some RAW post work would certainly help the leaves pop.
I hate to sound so negative, but the other shots are throw-aways in my opinion. I think they have failed to communicate to ME what you may have been trying to communicate. What you experienced on that walk was clearly more impactful than the last 5 images. I hope this is helpful, and not hurtful.
