Blacklabel ads query

Hi,
I had started using BLA ads.
Can someone tell whether this revenue generated is normal or i can generate more than this…..
Revenue – http://i33.tinypic.com/2qx1hjb.jpg
Top 15 traffic countries – http://i36.tinypic.com/zjj96a.png
Is there any other ad network i can use to generate more revenue. ?
Thanks
