Some new Illustrations :
that first one is stunning!
it looks as though there were some nice details in it.
give us a bigger version if you've got it.
the second one is nice as well,
but lacks the soft glow that the first one has.
try softening the light edge of the structure, and darkening the midtones just a bit.

Aye like em!
I think the second one's light sources are hard to read. The area in the front where it goes from bright to dark could be the trouble spot.
