Greetings!
This starts out sounding more like a paper about the author himself than about the three works. It is also a little vague just to say he has integrated symbolism; in what way has he done so? I think you need to move in a little closer with your opening; don't just tell what he did, give an indication of how he did it.
I can't tell you if this is better for a beginning, because you did not post the old version. :O-)
You say that symbolism plays a "vital role"; what role? While it is true that you don't want to give too much detail in the opening paragraph, you nonetheless want to be specific enough not to bore your reader with generalities. You are obviously a good writer; I think you just need to dig a little deeper with this one.
I hope this helps!
Thanks,
