Nice shots! I love the texture, but I would have used a little more DOF. I found the shallow DOF here to be a little ditracting from the texture ... crisp edges I think would have given the pics more punch.
just my $0.02 =)
Thank you for your kind comments, it made me look closer into the images.
Perhaps I should not have included the last image because I have not been critical enough with the focus. I have some doubs now when looking at it. But I like the other ones as they are. Adding some dof would lessen the mystery.
