Like #3 a lot. Wondering what it might look like to add a small circle to the front C to make it look like a cabinet know (in grey). I also like the way you did the text with the words aligned. That's better than some of the other logos.
I like the font that's used in #13 in my contest. Might like to see your logo with a similar font to that.
I like the dots you added but was hoping to see it on just the front most C (which would be the left most dot in the sample with the dots). I also feel the dot needs to be smaller and slightly skewed to match the angle of the "door".
