Please Help on Rating and Review

It has been a couple of month since I released my first app.
Now I got a few apps on the app store.
I see a lot of download has been made, but there are only a few rating and review on my apps.
So if you downloaded my app, and if they are nice app, or useful or you love it, please leave a rating or review on those apps.
Your rating or review would helping me a lot.
