Nice gallery and interesting content you got there - You are an architect or industrial designer?
I do have a few comments:
#1 The text on your "startpage" with photoblinds is a little hard to read. I think it should be a little "clearer" since it's a startpage. Perhaps set a more subtle, darker image? ... or change the color of the text through the theme CSS.
#2 The folders you have under "studies" all seem to contain 1 file. What are these files? Because there are images there, Imagevue thinks they are galleries so it tries to load/display them. It seems to me they are only container folders for other folders.
#3 You have an external link in the menu "digitecture org" that opens a link. Perhaps you should open the link in a new window since the user has no way to know they are actually navigating away from the gallery?
If you want to do that, add your link like this from admin:
