There are a few similarities but there are also significant differences. First, and I mentioned this before, your right elbow is too high.
Second, you do not have the same explosive power as Woods, which makes his swing so unique. Tiger squats down on his backswing and lifts up at impact to create an explosive blow that allows him to hit the ball a mile. Your swing does not possess that feature. I have seen both swings on video and to say that your swing looks exactly like Tiger's is a huge overstatement.
I would suppose i don't have his power because I'm a 14 year old kid.. he's like.. a 36 year old beast. I'll get there tho :)
I agree with you, though. He shoots down with his legs and everything and shoots back up, generating power. If you notice in my swing 2, I do that as well. Not as much as tower, because once again, I can't generate as much power as this 36 year old beast. He probably shoots a thousand more pounds of force and kinetic energy than I do. I wish I could do that, I could probably hit 190 with my PW, too.
