"CIO" looks low in quality, like i mean it's not smooth, you use three colours for the logo (I mean the picture alone). make use of the colour blue in the logo. if you have used some fonts to design the words "CIO" i recommend you to change the fonts
The HOST in that font doesn't look good, and the grey doesn't work either. I also think you should bring in the blue from the "logo". And you definitely need to up the quality. The edges are jagged and doesn't look professional.
