I love the colour scheme - that yellow. Pops of red but, mostly blue/grey/greens. I also like that it's not cartoony and there's some graffti/tagging that gives it a 'hip' feeling though I'm not sure I'd like a graffiti inspired font or anything.
Oyster is the name of the community but, I'd like to include "Canada" in the logo because that's the chapter - more as a byline or slogan than part of the actual logo. In future, there might be other variations like "Oyster Ottawa" or "Oyster Texas" for the other chapters but, we're going with Canada right now. The main logo lock-up or any symbol or image that's part of the lock-up should be able to live on it's own without "Canada".
