Conceptually, I like twoofme best. Possibly it is a little dark but so is the subject.
The photos with windows have either very dirty windows or windows coated with opaque material. The trees seen through the broken window are over exposed. Judging by the twoofme photo, you should not have any trouble fixing that if you shot to a raw file. Just process the file again with less exposure and use a layer mask to overlay the two exposures.
Not sure what, but the floating girl photos need something more to convince me they are not just photoshopped. Shadow perhaps?
