Yeah been a while since i checked DA. I got a job as an environment artist at Climax working on an XBLA title two years ago. They hired me more for my 2D skills and i learned to model and texture on the job. I wasn't getting anywhere as a concept artist and my art was feeling very stagnant a uninspired so learning something new was great. I always leaned towards the environment side of things when i painted so the transition wasn't too difficult. Putting props together in engine and composing scenes isn't too dissimilar to composing a painting.
My 3D stuff is still very sketchy but i'm getting better. It's easy learning to model but it's harder to model something with artistic merit, personality, accuracy, substance and style. I find that really interesting
Some people seem disappointed that I've moved over to 3D but in two years I've gone from nothing to Crytek. I must be doing something right
There's defiantly more jobs as an environment artist which is a massive plus. I actually still get to sketch quite a lot as well. It's a good route to take if you find yourself in a bit of a rut. You've already got the 3D skills and you're a better artist than me so i'd say give it a go. Who knows where you'll be in two years time
