1. The images are great. Nice job.
2. The signature in the bottom left is distracting and takes away from every image in which it appears...a lot. It is subtly telegraphing to the subject that you think you are more important than they are!
I really think you should consider a different signature...no one cares about the year and the name is illegible.
Recommendation to consider: If you are trying to prevent copying, put a larger image in the center of the image and fade it. If you are trying to "brand" the images, make your signature smaller and less distracting.
Again, love the images.
