Just found out this morning that there's been a change to the deadline for the ConceptArt.org EOW challenge -- yay! Even a few extra days will help me juggle these concepts in and around my job projects for a bit more polish.
Meanwhile, I've posted a progress shot from one of my Pern epic environment concepts: "The Mountain". I plan on posting a series of progress images here and on my CA sketchbook once I've finished them all. Lots to do yet for this, but you can see that I've done a quick pass on the background imagery, potential lighting and palette.
You can see the original thumbnail sketch for this here. OK, back to work!
