This one is... Curious.
I mostly like the abstract twang, but the cubes could be a little more varied in size,
I think it would look better if you buffed some and made some really small, I also
think maybe making them have slightly different angles might work. As of right now
they look a little too spammed.
You might also want to make the base of the tower, or rather, the cubes beneath it
form more of a circular shape, to make a smoother transition to the tower itself.
The light in the background could be thinned out more, what I mean by that is that you
might want to give the center of it a little more flare, and maybe make the cross a little
thinner.
Otherwise, neat one Heinvers, you're really starting to tickle the feet of us old guys,
keep the quality coming!
