The first is another jutsu for an airbourn opponent. This one requires that your opponent already be in the air due to one of your blows. You then appear over them, driving both knees into them to send them toward the ground. Which is cool and all, but then I'm the one airbourn, so I would then be at the same disadvantage. Kinda just trading spots with my opponent in a way. It probably has other uses I'm not seeing, but for right now it seems very situational.
The second technique is pretty cool. You appear beside your opponent in a burst of speed and give them a kick to their side. Fairly straightforward, but I like where it was going with the speed burst. That opens this technique up to use with anything that can be used to increase speed; LW, CM, SM, Swift, EIG, all could be used with this technique. Pretty cool
The third technique is really familiar. Like I can clearly see Vegeta doing this to Dodoria in my minds eye. Basically you latch onto your opponent, preventing them from escaping, by grabbing their arms with yours. Then you drive your legs into their stomach, winding them in the process, effectively stunning them while you do the rest. After this, you flip backwards with the opponent making them land on their head/shoulder area while you backflip to safety a few feet away. There's a lot going on here, but of you manage to successfully wind your opponent with the kick, it's all over. They would be fighting for air, it's nearly impossible to do that and keep up with someone moving like this. Very nice technique.
The last technique is also reminiscent of DBZ for me lol. This time, it's Coolers henchmen in the first movie. With this technique, you cover your arms in chakra that act as blades to aid in your taijutsu. Using regular, chakraless taijutsu with this attached can turn a mundane punch into possible impalement, or death. My mind is racing through the different possibilities now and whew, there's a lot of them. I see myself using this technique quite a bit lol
