I like this design .... but the colour should be more intensive, powerful and more striking. And maybe the X of xcitedent should be in the same size like the rest of the word.
The new version looks better but the colour should go more towards violet. The tooth should be designed a little more fine. A little more lifestyle. "Dentallabor Axel Gütges" maybe looks better if its written in white like in the first version.
