Thanks. I like this one too and I was quite happy with how the lith print came together. Probably the best lith I've done.
One advantage of living in a place that's usually partly overcast is that you're never stuck with the same lighting for too long; just wait for the clouds to move around. It helped out for this one; at first it was too dull but I just waited three or four minutes and got some nice light on the leaves.
