doublehammer - way too stiff in this replay. You also hold the same grab for a long time. That is not a good thing. If you are going to use grab then only use it for a few frames, just enough to get Uke into a position where you can do more. Your hits are also not very clean, make sure you are hitting exactly the joint/s you want to dismember
manip.-boom - Pretty good replay. My main criticism is that you keep your left knee contracted for a while before kicking. This doesn't look very nice. That said, the actual hit was quite nice.
So here are a couple of new ones. New horizon is definitely not finished, so ignore everything that happens after the decap.
