I'm glad you like it.
#48 - with the black tagline
#49 - with the black tagline and the faces flipped and rotated a bit so they look a bit like letter "S" which stands for "Suite"
#50 - Another approach with the faces incorporated within the name between words. I also skipped the word Melbourne so the city is name is not duplicated. Instead, I emphasised the city name within tagline which can be easily replaced with any other city name without changing the overall look of the logo. Just an idea.
