I think that copying another artists work provides an important variety of learning processes. For me, it was integral part of my learning how to paint on so many levels. I found that the process of copying did not change my style, it simply enhanced it. Once I got past the moral notion of copy, I was able to learn more about paint and painting than ever before.
Little techniques that I was able to pick up...
I believe that the paintings that I want to copy, are already part of my aesthetic understanding, insofar as the way it speaks to me and how I see the things I see.
I wish I could remember the painter of this piece... alas this was done in 2001 and my memory does not extend to that distance actively. That said, I still use the notions I learned by way of making this painting in my current process.
