Quick design alterations I would make:
• Top right nav <a> color -> #FFF
• "Desperate Houses [this text]" colour -> lighter yellow.
• The "Read more +" buttons are slightly odd, shading on the top is confusing.
Actually won't list them, just take a look at your contrast in general. Your colour scheme is friendly and distinctive, just not implemented very well.

Just a tiny (tiny) point, the hover state for the top right navigation is on the <li>, instead of the <a>, and your <li> is bigger than the <a>, leaves a deadzone of about 6px under the links.
