Hi, Lane. I think that you should go back closer to the POV you had before in the tower example images, for the following reasons...
Not that this one lacks anything at all, it's really cool, but to truly appreciate the scale of this f*cker, I think it's best to see the detailing of the surface and the minuteness of everything else around it in comparison. Do you know what I mean?
I just think if some kind of everyday objects are used as a comparison then, the entire scene-render seems all the more 'BIGGER', know?
What I mean is that, if you have the tower at extremely large scale(and as the focal point, as before) then really tiny views of skyscrapers and trees and such would accentuate that all the more.
I'm not knocking this at all, though! I think this is really cool!
This is just my first idea of seeing both scenes together now. The first ones seem *MASSIVE*, this one, not so huge. Is all I mean.
Hope you get what I'm saying, it's not meant to downgrade this render at all.
