Was looking through old stuff on the HD and found some enviro studies / classwork I did about a year ago. I took an environment class with James Paick , who along with being a terrific artist was also a great teacher. These were done through the CGMW - and I do hope to take more classes. It's not cheap, but totally worth it from my experience.
Environments, and perspective have always been a weak spot of mine, but I did find improvements since this class. Just need to keep working on it.
