Just yesterday I found this amazing gallery on DeviantArt by one I.L. Jackson. Total it is 35 pages of awesome sci-fi art, but the ships in particular are what caught my eye...all 10 pages of them. And best yet is the fact that most of the ship designs are his very own.
The artist (who is also one hell of a writer) and I exchanged a few notes and he notified me that he'll soon have a web series coming out called Ascension Chronicles. Be watching for that!
In the meantime, be sure to check out his art. Do yourself a favor and read every word of his descriptions too. They give nearly every pic the oomph of an FTL jump.
