I beg to differ.
Yoshi "Smack" 1: "notice Mario's hand on the side of Yoshi's cheek, and Mario's body beginning to turn to the right."
Granted, Mario's hand is on the side of Yoshi, and his body is turned to the right a tad. None the less, Mario could still very well be pointing.
Yoshi "Smack" 2: "First, ignore the thing on Mario's hand/behind Yoshi's eye. Thats the result of my ****ty digital camera with a rapidly dying battery. Mario' bdy has definately begun to turn to the right, and Notice how the hand is higher and at an angle more towards the left."
Mario's body has made no change what so ever. He has not moved at all since picture one. He is no more turned to the right than before, just look at the two images, the exact same sprite. I also notice no change in elevation. His hand has stayed the same, where Yoshi's head has gone down. No movement of the arm or hand. I don't see a change in angle either, considering it's exactly the same as in the first picture. His arm is in a straight line, no angle to be seen.
Yoshi "Smack" 3: "Notice how the head is down and sticking out. Most importantly, notice how Mario's hand is underneath his chin. His arm isn't being drawn back to his side, IT'S GOING ACROSS HIS CHEST!!"
Yoshi's head is also, in the exact same position as in image #2. His head is no lower than before. I can see where you would think his hand is making the turn, but I still believe it is being drawn back. Notice the bend in the elbow, that is where it makes his arm seem to be making the motion around. But, in either of the two images before, a bent elbow is absent. His elbow would have had to bend before image 3, but no sign of it has been shown. I see his arm being drawn back in a casual fashion.
