If you do some finetuning, i love your idea!! = )
(Some of your skyscraper look a bit like a candle in a very small view, but i love the design and your idea!)
like it a lot just turn the "C" a bit ;-))
As Joana said, try to rotate logo in left a bit that it would look more upright. However, very good start, it looks very nice ;)
I think this could use some fine tuning. For example the angle on the arrow looks a bit off.. But keep going with it, I see potential!
I really like your idea. I would turn the C a bit though.
