Great progress, looks really good, much better to see a complete movement pattern.
Here are some movement pattern which looks really good in my opinion:
0:26 Neutral split step at the beginning, scissor to the forehand backcorner, thought you should have finished with a neutral stance/split step.
0:08 The movement pattern to the backhand looks really good (including flying step/fei bo?). You still do a very directional split step, thought it helps you to push off more powerful with your right foot, you still need a lot of energy to rotate your body. To reach the backhand corner you need to move closer to the side line to take the shuttle overhead, therefor a more neutral split step could help you to push you more in the direction of the side line.
1:16 I'm unsure if this is intented, but you sometimes included a china jump which is a faster(?) way to reach the forehand corner, atleast to intercept a shuttle early on. You should include this more in your routine. A more neutral split step at start and end could help, you have a lot of body rotation at the start of your movement.
In general I think that the start and end of the movement pattern is something you should try to improve. There's the danger, that you reinforce a bad habbit by repeating it during training. The bad habbit is in my opinion the really pronounced directional split step, this leads to a lot of body rotation at the start of your movements. Time and energy you could spare, if you would start with a more neutral split step. Maybe it would be a good idea to make two split steps for a while, that is
split -> movement -> back to base -> split
little break
split -> movement -> back to base -> split
..
Although check the distance, how far do you move ? From your base position you only need to cover roughly 2-3m. It is a good idea to reach behind the shuttle, but if you move too far you open up your court.
When I do shadow footwork at home, I place some marks at the ground to check my positioning.
