*As you grab my right wrist, I retain a grasp on my sword with that hand - however, using my left hand I do the same to you
(from what I'm reading in your move, your right arm is held near your head, holding the hilt of your sword which is pointing downwards - you left arm is down by your waist, near the tip of your sword).
As you go to make your step to your left, when you start to pull me towards you, I throw my body forward, tackling you to the ground due to the added momentum, and headbutting you at the same moment, preventing most of your move as I have a hold of your left wrist, and you a hold of my right, and - well - you're on the ground, grappling.*
That was actually very well done. ^_^ Took me a bit to figure out what I wanted to do.
And about your note: Not very good, truth be told.

' What you just said doesn't make a lot of sense, and doesn't flow well from a Taijutsu/Kenjutsu stand point anyway. @_@
Anyway, if you're ready, we'll move on to diagonals. ^_^
