Definitely a subject which works well in B&W, but the image itself has a couple of issues in my opinion. It's slightly under-exposed with a definite blue caste (cold WB) and isn't quite straight in the image. Additionally, the patch of branches(?) lower RH corner are rather distracting and could do with being cloned out and the DoF seems a little shallow, as the neck area appears soft.
The conversion isn't bad, but suffers from the under-exposure of the original which is making the dark crystals in the granite stand out more than normal, and give the statue a very 'spotty' appearance. I think this one should be reshot, and perhaps bracket 1/3 and 1/2 stop over and try again.
Just my $00.02 worth - your milage may vary.
