Piee, your replays were okay for your first.
Nothing special for your first one.
The next one was better, like Pat said, you were twitchy in last few frames.
Move a lot of joints at the same time was okay but don't make your body stiff cuz of it.
For tricking, yea, don't move a lot at the same time. It will make your body stiff and you will not get a smooth movement.
Btw keep training Piee.
