Instead of editting the replay and having it done for you, I'd like to give you a few tips to help you accomplish this by yourself:

1) Speed - If you are planning to possibly use this opener in multiplayer then I suggest you use a much faster move. Favourably one that touchs the oponent (with a reasonable force and speed of course) at the first/second turn, depending on the turnframes.

2) Momentum - You're going to need to obtain a lot more momentum (an impelling force/strength) to gain a dismember. Try rotating the chest, lumbar and pecs effectively to get a good build up.

3) Joints - Even the slightest details can give you a better chance of dismemberment. Try grabbing/ungrabbing, contracting, extending, holding, relaxing the wrsits and ankles to get a more accurate or powerful hit.

4) The butt - I can see you've been extending the glutes - good start. Extending the glutes are good for kicking, but contracting, holding, or relaxing the glutes can be even more useful in different situations. Try experimenting with them and see what you can achieve.

5) Relax - Again, good start relaxing, but as you move more and more joints I would advise maybe holding or relaxing a few in place. This can make the replay a lot more fluid and generally more aesthetically pleasing.

6) Targets - My last point you may want to consider - you don't always have to aim for the joints themselves. Sometimes you may find getting a dismemberment easier if you hit between the respective joints.

Try using a few of those tips and see how you get along, you might feel more comfortable using some techniques rather than others.
