looks good~ I love your building~ especially the front ones~ and those far far away ones, I think you may do some more changes, they all looks without too much difference 
excellent so far
very nice very nice very nice …!! you have great modeling skills !!
It looks really awesome! I can’t wait till you add the characters and really make it come to life!
Your idea reminds me of that District 9 I just saw recently just replace the aliens with robots.
It’s shaping up nicely.
