I like it.
In image 1 there should be only three towers though. The leaning one should be removed. I think they should be stuck deeper in the ground too, the bevel at the bottoms should be hidden.
The thing I don't like really is the light beam from the moon, which is interesting as a concept. But plays badly in this still. Perhaps as an animation it would be more justifiable... Like the lighting of the signal fires in the LOTR film.
You asked if it was familiar imagery in some way. I would say 'HALO' comes to mind a bit, and maybe '2010'. The difference is the HALO structures Im thinking of were smoother surfaced ('2010 also). But Im stretching a bit...
Personally I do *not* find this image to be derivative.
If the image is familiar this is a good thing not a bad thing. Art is a language, and speaking in a way that people understand is the point. It is very hard (nearly impossible) to create an entirely new way of speaking, visually, in the first place. It is even harder to do it and have what your saying be understood by anyone.
You made a science fiction image that has your own voice, but is heard in a language I understand, Kadri. This is the point, is it not?
I think one issue is that you are releasing your images as separate works. Whereas ideally, they should all be viewed as part of a series at the same time.
Once you are finished, you should post a link to a collection. Or better yet, print a book (there are more than a few ways to do this for cheap, with good results).
