All the designs are really nice, simple, clean easy to use ( although the use of Google translate was needed ), but again, as regards to design, they are really nice, well done..

I think the idea behind the site is pretty good, if you can find a theme that better suits what you desire, it should make it easier for you to make it fit exactly what you want.
I like the panelled look to the site and once finalised it could look stunning, maybe you could try make it a full screen site, maybe horizontal scrolling, just to make it stand out more.
