#61 - like the fun look and how you linked the speech bubbles. Would be interesting to see softer font and small caps. maybe add a bit of colour to give subtle warmth.
We would like to see #78 with "&" used in the tag line and capital "C" with Centre...perhaps spread out "Speech & Hearing Centre just a touch? looks a little bunched up. Otherwise, looking sharp.
#80-84 - it has been mentioned that the symbols resemble an elephant - we like how it's supposed to be a an integrated speech-bubble and soundwave/ear. Wonder if you can revise the symbol to make it look less like an elephant and more softer looking?
Also, we like the use of "&" in the tag line and capital "C" with Centre.
