Wow! This is cool! I love the two level text. I love the colors of the text. I love the older dentist. I love the tagline running under the "BestPractices"... the font is great. I like the font.
I think the head gear for the dentist may not ring true for dentists... not sure what they have on their head, but that head gear makes me think of a 1950's doctor.
Been thinking about the web design in connection with this design... I like the background color... it helps the little guy stand out. I think it leads to the sense of stability and trust. I think the way I would implement this is to treat this logo as a banner, with the color fading to white on the bottom... thinking out loud... Is there a way to make the logo standout on white background?
I think I like the glasses... the smaller ones. The more I look at the designs, the more I like #8 Very clean... I wonder what it would look like without the tagline...
#11... I wonder what the blue would look like in the tie and OnlyTheBest if it were a bit darker... not sure if I would like it... but it might standout even more. I like the white background... it is really clean... and I think the tagline is not needed.
