I've always found landscapes are the most difficult thing to do. You need to distill 2-3 hrs of a constantly changing environment on to the canvas. These are mostly work from the past. I do have some current work that I'm battling with, nothing I want to post at the moment though. I hope that will change soon.
Update-May 8th, 2012 I am in the midst of revising much of my online representation (this blog, my website, and more) and for now, you can see an updated album ofland/trees/sky here.
