You are right about the photo of the ivy: it is largely overexposed.
While I'm not too fond of the first photo (personally, matter of taste, I think), I like the second very, very much as well as the fourth with its hard contrasts. I'd only wish for the person in the second to be more on the way so that it would not blend into the wall so much, but hey! You can't have everything.
I can't quite figure out what we see in the last photo, though I must say that the texture of the planks (?) comes out nicely.
