Ok, I've seen Kobe's sig shot on webster's roster and I have to say its way off. But I know exactly what you should do to create a perfect one.
1. First of all use Ray Allen's shot as the base. The way Allen holds the ball is exactly how Kobe holds the ball. But here are differences and I'll explain them in the next steps.
2. The first difference is the follow through. The follow through should be like richard jefferson's in which both arms flail forward instead of the right hand kinda sorta stayin in the middle. So just follow richard jeffereson's follow through.
3. Next is the legs. The legs should be flailing forward instead of staying stationairy. The body should also be fading away a little more.
I garuntee you, when making these adjustments, you'll have the perfect Kobe sig shot. Please someone try to do this. Pleeeeeeeeeeeeeeeeeeeeease.
