Just some small nitpicks on the model:
First, the Backpack flap is a smidge longer, going down to halfway or so, as shown here:

Also, the backpack straps reconnect at the bottom of the backpack, not about halfway as seen in the current model.
Finally on a color note, the backpack straps are red, the armbands are orange(The image shows a yellowish color, and the vid shows red), and the most nit-pickyest of all, Jazz's eyes are blue.

Other than that and what has already been mentioned, it looks great.
