Petr, I love this image. I'd prefer a less intrusive copyright sign as it really takes away from the image IMO. Lovely light - excellent DOF. Might check your whites on the orchid to the left - they feel close to being blown in places but wow, what a gorgeous photograph!
Hey Petr, this is really nice. Good comp and the color combination really works well.
Jules is right about the large copyright notice taking away from the shot. I gave up putting a copyright on most of my images. Honest people won't use your images without permission and dishonest people can easily clone away the copyright.
