well, fyerr, I like the amount of force behind the hits. They are indeed POWERFUL and you do a lot of damage to uke, breaking him into many pieces with a smallish amount of strikes.
That being said I would have to disagree with Baku and say that the lack of style was the major flaw I see in these. The first one was different, you had DQ on and got the job done. The last two though, were very stiff, and were mainly you grabbing uke and swinging around him. Its an easy habit to get into, but after so long it begins to get tired. My suggestion is to maybe try letting go of uke sometime very near to when you strike, this should still DM, and it will open you up for more possibilities.
