It surprises me that this is a pastel, looked like an oil painting on first looking at it. This is a good size of work, most of all the work has atmosphere, you have captured the heart of the forest.
You did a great job differentiating all those greens. Caroline is right - it does have the feel of an oil painting!
This was a job for two days O;-) Perhaps I've read too much in Richard McKinleys book. Hm, must a pastel look like an pastel painting and not like an oil painting?
