The movement looks good, except for after the first hit, you shifted direction. I know it would very hard to keep the flow, but you just completely reversed it.
The first hit was a nice slash, looks pretty clean to me.
I hate when people hit Uke when he's on the ground, so I did not like the rest of the replay.
Also I think that sometimes a replay that's very smooth looks slow, but it is not slow. Might explain why Noroma thought so.
But I found the second kick to be weak too. You had a lot of power on your leg, but you didn't really "hit" Uke, you slashed him, so not all of the momentum was used on the impact.
