How to improve your photo
Once you get the angle that you think works best, don't be afraid to step a little right, left, backwards and forwards to adjust the view slightly. Sometimes it makes the image stronger, and other times it doesn't work at all - but by trying different things, you learn regardless of what makes a photo stronger and/or weaker in the process.
Seeing this shot, makes me want to attempt it myself in B&W. The original is a little dull in colour - so the PS technique you chose has really set it apart. Give B&W a shot in PS, and see how you can improve further on that original.
Leonard, you've done really well with this image - exposure, lighting and composition have all come into play and you've executed your technique beautifully. Well done - this is certainly a favourite for me.
