This looks right. The last 2 terms would produce an EXOR operation. Remember:

$$A'B+AB' = A\oplus B$$

Nothing else comes to mind when simplifying this further. However you can refer to the attachment if there is anything else you can do.

$AA = 1$ is not correct.

And there seem to be other possibilities at the top line - consider what is $ABC + \bar{A}BC$ ?

Let me encourage a little further and say that I agree with your work until the fourth line, adnankhuram. From there you can make further simplifications to leave something that looks like $PQ+RS$.
