MLS exposure typically has about a 70% success rate. That means approx. 30% of all listings that are on the MLS will not sell. This assumes, of course, all other things are equal. What type of other exposure do you have? I don't even see your home advertised on this website - http://www.trulia.com.
I don't see a virtual tour. The pictures are also blurry. Is your home advertised on google, yahoo, msn, aol real estate, etc? what you need to do is find out what your realtor is doing for you beyond the minimal MLS exposure.
How many showings have you had? If you've had a satisfactory amount of showings, then you'll know that the issue is something with the house once the prospect is there. If you're not having a sufficient amount of showings, it's probably due to your lack of exposure.
