Melbourne Meerkat

This morning myself, my cousin and her son all went to Melbourne Zoo on what was a pretty ordinary day weather wise. And thank goodness we went when we did because it got extremely windy and wet later on in the morning! So unfortunately we had to cut our visit short but not before we checked out the meerkat enclosure. I noticed this particular meerkat resting against the wall on it's own and I knew that his was going to be my photo for today. I've tried to think of the 'rule of thirds' in this shot so have I been successful? What are your thoughts with my photo today?
