I could swear you posted an uncoloured version of this some time ago, yet now I seem to be unable to find it.. Most likely I'm just blind or not searching hard enough, though.
Anyways, very nice work. The colouring is neat, and especially the glow effect looks rather great. The colours of the sky could differ a bit more from the crystals, however, now they pretty much blend together.
Funny thing, by the way: the name of the area is Red Zone, yet there isn't even a drop of red in the picture.
