Could This Be Art?

OK I have had this argument so many times about the question "Is this Art?".
So I'm also asking, "What is Art?". I feel art is the expression of one's self and emotions. The way I feel determines the kind of pictures I take or the type of painting I paint but for the mere fact that it expresses what I feel, I consider it art. So what brought about this topic.....
.....A couple of my friends and I were snowed-in earlier this year in my house. We were having fun but we were still bored cause we kept doing the same things over and over and over....OK let me stop LOL....over again! Dancing, Drinking, etc. Due to our mood, "BOREDOM", we decided to create a sculpture out of empty mountain dew cans and some other "necessities". Basically, this sculpture was to portray or show the things you really need during a snow-in. I didn't have my camera so I used my sister's Sony Cybershot DSC-TX1.
Pretty decent camera if I may add. Anyways, this sculpture was created by myself and my friend Deroju. When we were done I felt as though we just created a master piece so I took a picture of it and put it on facebook. I got good reviews but some people asked me, "Is this Art?". I think it is but do You?!!?!?

Feel free to comment on it......

So I'm asking.....Could this be Art?
