My favorite of the designs you've presented is #27. That being said, The tail seems too abstract to look like a D. Many people could read it as Foxy Oesk.
Additionally, please try to use black for the word Foxy.
Please let me know what detail exactly you don't like about entry #63, because i saw yesterday Fracco submitted part of my concept using letter "D" as Fox's tail and you ranked him 3rd and more i do i can't do better than 7th place in the rank? is there any way i can improve my work for you, probably you need to see it more WEB 2.0 look with effects, thanks.
