wonderful shot! The conversion to b/w is great. The shadows are nicely done. And i especially love the curve of the hill. Maybe you could have lowered the vignettes, just a touch. Overall... great shot!
I like the way you bring the grass out.. it looks like it is in the same ground as the tree, the naturaly blended B&w textures are wonderful! It make's me wonder if the lithing was that way ore if you edited the curves. Great job!
