#3 is my favorite; love the composition. not in love with tone and would like to see them in B*W.
your signature adds nothing and distract from the beauty.
It also deters (somewhat) folk from nicking them! As someone who is constantly attempting to stop the flow of copyright infringements, I have found those images which are watermarked right through the centre are rarely, if ever, stolen.

One of my images I placed in my Fred Miranda gallery many years ago was unwatermarked and I am still battling the massive infringements to this day.
