Thanx Mumul, that #21 really wasn´t bad, if I could put 2 logos on the 1st place, I did it.. I like #21. But letters straight and more recognisable.
I am not a designer, but - there´s a place over .cz, what about to place there that 4leaf clover, but modern (futuristic, more like 4 rectangles than 4 "hearts") and the same colors like logo?)
Great work, really..
