Having taken a hard look at all three shots, my preference is for the b/w version cropped in a square format - the composition better follows the rule of third. Unfortunately, I downsized the picture too much and lost resolution. I will re-post a higher quality version this evening.
Let me know which one you prefer in the meantime, I am interested in your views.
Thanks for watching.
