I just visited your site. I have to join the minority, and say that the watermark is not very pleasant when viewing pictures. I would suggest a simple service to monitor your images against theft rather that a disruptive watermark that wont help sell the images. I did a brief search and one such service I found was Pixsy, but I am sure there are more.
Also, find someone to proofread your content - grammatical errors do not add value, in fact it makes the page look very amateurish, which is the exact opposite of what you are trying to convey.
Pages that you have not yet set up, edit to show they are in progress.
This can end up with a very nice feel to it, so keep up the good work
