Critique on B&W conversions

Hi All,
I would appreciate your feedback on the conversion of these images to B&W. This is the first real time that I have manually converted an image (rather than using an action or preset).
The conversion was done in Adobe Lightroom. I'm here to learn (especially about B&W)!!!
Image #1
Image #2 (more fill flash!!!)
Image #3
BTW - feel free to comment on the image as well if you like, but I already know what is wrong with them and know they are not the best
EDIT - updated with colour versions as requested by Oz
Cheers,
W00DY
