I haven't listened to any previous version but I think this tempo is good. It does sound a bit choppy though. To make it more flowing and musical you should think in phrases rather than notes or measures. Imagine signing the melody line. You start a bit softer and then it grows to a high point and then tapers off. The final phrases should be like an echo - much softer.
A few comments about your technique. In the LH you are using too much finger movement and not enough rotation. Your hand arch is too flat and your joints are collapsing. Go extremely slow and observe your hand shape. The knuckle joints should be the highest point of the hand and make a nice arch, and when you press keys the last joint of the finger should not collapse inwards. It's better to practice slowly with correct form than try to go faster and ingrain bad habits.
