I apologize for getting back to this so late.
I can use your video for reference since I'm not exactly great with figuring out how to record stuff on a computer.
The first combo with the Spiked Cleat Kick at 0:02, the two enemies beneath the Morning Star Drop Kick at 0:06,
The hit stun that occurs afterwards lingers a bit too long. I feel you could reduce the amount of hitstun time on the enemies by about half, though I could be overestimating.
On further inspection it seems to be happening whenever an enemy's movement forces them to collide with a surface, with the enemy at 0:02 bouncing off the invisible wall at the right and the two at 0:06 probably colliding against the floor, though I'm not exactly certain!
