OKay, so these heartless bunch of reviewers don't like your style so i'll try be be gentle in my critique. To be honest, I flat out agree with them, but I'll point out (visually) where your going wrong.
You like the colour blue which is fine, But try to start a styling project with a 3 colour usage system in mind. You've implemented so much blue in this style it's hard to focus on any areas and determine which colours or what type of theme you want to go with there's just no reference point to suggest anything.
I'm not really sure what to suggest because i can't see any other colours which i think you want to use. Opt for a 3 colour system implementation with the 3 colours complimenting one another (look at the major vb styling providers for tips) you'll also do good by viewing some styles here at the org for that inspiration.
