I really liked it, and like TServo said, it was like watching the OT whenever Obi Wan was in frame.
Is there any way to make Yoda sound less deep. I understand as a person gets older, their voice deepens, but younger Yoda and OT Yoda should have the exact same voice. I don't know how you could pull it off, but raising the pitch about 5-10 % and taking some of the bass out of it would make him sound like he dropped right out of ESB or ROTJ.
