Entry #49 is nice. It would have been great if the tooth logo's height would have been the same height as the writing on the right side or maybe a bit longer. It makes making actual signs for the building a bit easier.
#55 and #54 looking closer. I think the DENTAL part should be thicker so it shows up better. The font for PhD can be improved. I am looking for a more "professional" more "corporate" font.
