Marek...first..."tip of the hat"...for doing the hard work of going out and shooting... and getting site up and running! Few comments
1. In art..."red proceeds, blue receeds...". This is a concept worth considering when you choose banner graphics such as the "
www.travelogy.eu" above your slide show. I find this is very very distracting...while I'm looking at your photos...this blob is always "leaping toward my eyes"...as if to say..."pay attention to me only"...not the wonderful photos. I think you want people to be concentrating on your photos. I would consider eliminating the red, elipse blob (your menu text colors are a shade of red too) - consider something that lays back more.
2. I don't particularly like the "website" as your banner info.. You have a very interesting, and very memorable name...why not put it above the slideshow...and let the viewer constantly connect the moving slide show...with Marek Kubinek?
3. travelogy...sounds like a travel agency to me...
3. The info below the slideshow is a bit cluttered...but if the banner was better conceived perhaps...then I could live with it.
Good luck with your work, and your site...
