Hi ake,
these are some very good concepts. Like your work very much- thanks for your ideas!
#24 and #25 look very elegant, but I like #26 to #29 better. I`m more into modern syles and fonts.
#27: The circle looks good, but maybe it could look more like a tooth or a smile.
I also like the idea of capital letters.
Could you please enlarge the word "ZAHNARZTPRAXIS" a little bit, so that it doesn`t look too small regarding to "DR.Dörter"
Thanks again!
PS: The concepts I like most in your portfolio are #1(client rank) Paramount and #2 Mutti Dental. Both signs look great. Especially the heart and tooth combination is fantastic.
