My only advice is simple. You need to put more momentum in your jump. When you plant both feet before takeoff like that you're essentially stopping, canceling out most of your inertia. The same can be said about your landing. Try to land with one foot in front of the other, that way you're running on your exit.
Other than that looks good. Once you learn to carry momentum into your kong you can stretch out the dive distance and learn to vault some longer obstacles.
Keep it up!
