I prefer the colour picture. The colours are prominent and add a lot. Is there a vignette added to the mono version? I'm not so keen on that. It makes it 'claustrophobic'. The colour one cropped like the mono one i would say.
I lean toward b/w, but I bounce all my photos off my wife before I post them on Flickr. She see's things a bit differently like an average person and prefers the color version. Her input is valid for me. I posted a few other marina photos on Flickr both in b/w and color, but I'm stuck on this one.
Here are 3 versions in b/w. (One is in my initial post above.)
Which of these 3 works for you?
