Even if this wasn't a stolen image...
I'm not sure why we "couldn't critique this?" In addition to learning copyright laws and ethical conduct, I suggest learning what it means to actually critique something - especially in the artistic sense of the word.
I'm not saying that to be a smart ass, just friendly advise from someone that has probably made similar mistakes. Take time to fully understand what you are trying to say and, of course, take the time to give credit where credit is due. Everybody will be happier for it, even you. You should trust me on this because I'm definitely older and possibly even wiser than you.
