Original image needs cropping, IMO. It's a little junky on the right side of the frame, there's a little too much foreground and the composition is a bit static because the subject is almost centered in the frame.
The B&W version is showing improvement, I see you've cropped the right edge and removed some of the foreground, much better. The subject is still a bit too centered in the frame, though, and I'd still crop the left side of the frame a bit. The subject will still be too centered in the frame but some isolation will help, I think.
