I think we'd benefit from some beginner explanations on what op is demanding. Specifically on this assignment:
>>4) Framing, i.e. doorway arch, hole in the bushes and so onFraming by this definition is not framing as in general framing that you do on every image. It's framing as of a picture frame with picture frame in the image. Or an image of a window looking out, a door used as a frame, or even central subject with everything off focus around him. It does not need to be square, it may be circle, or any kind of implied frame that is present in the image.
Not to go offtopic by posting images that don't fit required time and theme parameters, here is only thing from this month that would fit the description. I am sorry for the poor execution. But I hope that you can see that I'm using beech trunks, and leaf foliage to frame the vista beyond. You can find better samples of what is being talked about in the following link in paragraph that talks about frame in frame framing:
