The Design is good and I like the "mosaic". Can you punch up the color?
I like the change. Can you Saturate the colors and make them less pastel? With the second entry the name of the company gets lost. Either make the C's larger or more saturated in color than the "to". Can you move the name to the right of the logo and make "classic to contemporary" larger. I like the logo a lot and am getting really great feedback from friends on the logo design. Feel free to change the colors. I mentioned black, red, grey and purple but by no means am I locked to them. Purple, brown, blue and green might be awesome together.
The Red still reads as a fuscia color and at first glance the name of the company does not pop correctly. It looks like the company name is ctoc. It should be obvious that it is C to C.
