Very sporadically, I am working toward a range of Martian features.
Welcome and good start! :)
Middle one is very nice. Good sense of composition and great structures.
These's are really cool! Love the old camera effect. I wonder if you could get some of that old film type pix elation in by using a duped layer, dissolve it some, rasterize, and then blur it ever so slightly and overlay in with some layer opacity. I tried with film grain, and it just looked like film grain but not the contrasty broken up look of the actual image elements like in those old super high contrasty images.
