Thanks for the great comments. I always like posting here, primarily because people are really supportive. I hope that what I drew was close to what you envisioned. I really look forward to seeing Jennifers work too!
To answer your question, I used Photoshop to draw the terrain. I've been playing with it for awhile. Each time I do so I seem to get better and better. Whats interesting is that I've had that cliff and about 4 others for about 2 months now. The North Cliffwall has been something I've worked on and off for that long, and now I just got to posting one of them. While the Cliff is pretty cool, Im really liking the new stuff that I have been working on. My goal is to start building up my skills to production level quality, I think Im still pretty far from that. But while I play with it, I wanna make sure you guys get some goodies too.
