Based on the piece Pillars of Hope this is basically a similar system of planets thrown far from their original home due to a collosal super nova. They survive now thanks to the pillars of life that emit a regenerative radiation that sustains life on the planet.
Coupled with the giant habitat towers these planets are full with life.
Used that nebula piece I made and made it better, added some more aspects like a super nova remnant and a contrasting coloure, unfortunately due to a photoshop cock up I was unable to work on the nebula further as the PSD file became corupt for some unknown reason, fortunately I was able to open the file in illustrator but only as a flat image.
Anywho Im actually happy with how it turned out, a soft and rather calm piece.
