1 and 3 are really nice images - both got nice and contrasty colors. And the composition work for me.
Only complaint - just think that your watermark is a little 'too much' and takes a lot away from enjoying the images.
But, I know these days we all want to protect our images, so I suppose this is the price to pay for it :shrug:
Still - lovely shots and I am sure without the watermark they are even better!
