Formally--that is on the sensory level, these images are interesting and pleasing. However, once the eye is drawn in, I don't know that you have yet given the mind much to do. Like most formal art, it offers itself for consideration, but doesn't provide much except for a locked box for the mind to puzzle over. There is a suggestion of meaning, but nothing concrete for the mind to grapple with. If you'd like to continue working with the abstract, look for more details that might suggest a little more to the mind. As noted above, the contrast of materials in no 6 adds brings into consideration ideas of materiality, it adds a slightly more specific time to the image, so someone might consider the social component of changes in material in building as distant signifiers of other interactions. These of course would be leaps, but that's the game of abstract art. Suggestion without definition. We might say that the more suggestions an abstract piece offers, the more open it is. The fewer, the more closed. These are extremely closed.
