Very nice shots guys!!
Brute your watermarks are def better in the last few. It is always a tough balance between protecting your work and not being distracting.
There is a program out there called GIMP that is a free to use graphics program. It runs a bit like photoshop in multiple layers etc. a touch of a learning curve if you are not graphic software savy, but there are lots of youtube vids. That is what I use to watermark now as it lets you really subtly lay it in over the picture content without being tooo distracting.
