I see the bends. It might be that they look unusual since you're a lefty playing upside down. So where a right handed player would push up on a string, I see you pulling down.
Well played, sir!
BTW, I agree with Rob. I hate it when people do their videos in portrait mode. Then they post it and you get a third of a picture when it's viewed with those crappy boxes on either side. Then it gets picked up by some TV station and they post it with some blurry pixelization on the sides. I remember when people would moan about the little strips of black when you viewed a widescreen movie on a standard 4:3 TV screen. Screw Youtube shorts! You've got a high def camera that can record in widescreen... use it!
