A good start in my {professional} opinion! really like the idea of emulating the STi logo!
To be brutally honest though, the 'c' could do with a second circle inside it to continue the theme and unfortunately the 'b' looks like an 'r' to me... Wouldn't take much to sort it though.
Happy to cast an eye over it later this evening if you like?
===============================================
Had a quick look at this one (hope you don't mind) and the result's below... didn't add the second circle inside the 'c' as although it fitted with the 's' more comfortably, it made the creation of a 'b' nigh-on impossible!
Anywho, not changed a lot, just made the 'b' a bit clearer and pulled out the text slightly.
Hope it's of some use?
