This logo is very good. First I thought I wanted the big rounded shape to resemble a letter (maybe G) but then I figured it subtly resembles the 'O' and then I realized it doesnt have to resemble anything at all, since the rounded shape already suggested the 'O'.
I like everything I see here. I hope your client is happy ^^
Thanks! I went through the same process too, thinking that I should show an 'O' and a 'G' but that would make the logo a bit complicated so I just made a subtle resemblance to an 'O' and a mirrored 'G'. I don't want the client to be 'bound' to a letter since that would mean that the other word weighs more than the other. Glad you liked it, as did my client.
