TL; DR, Work on your rotation and the flow and twitching will sort itself out.

A few things i see that you need to work on, twitching nothing drastic but very noticeable. Rotation very noticeable, you rotate your chest too much and it doesn't allow you the freedom to move as much as you should be able to. Compare your movements to torified, notice how his shoulders turn a minimal amount in relation to his hips, keep them squared when possible as much as possible. Last issue i see it flow. To an untrained eye it would look like your flow is great, mainly because your limbs are always out stretched and moving quickly, but in fact it is quite all over the place. This is mainly because of your choice of attack and movements which are probably caused mainly by the bad rotation of your chest.

@Marrez i feel you on that bro, i dont even like sparring and that's the only thing enjoyable for me just takes so much energy out of me nowadays
