cool replay
i'll highlight in order of appearance what i like and dislike at specific sections of the replays, as well as what i would do instead, as a Professional Ukebasher
the opener to decap i think is pretty sweet, honestly. if i can say anything, i would say to watch out for when your tori crumples from awkward positions though. if you look at about 940~ you can see that the glutes are in the opposite positions and the lumber is heavily bent to one side, this takes away quite a bit from the perceived power as well as making the start look a bit careless due to a lack of setup beforehand
the decap itself is sweet and clean, but i feel again, the perceived power has been taken away due to the immediate contraction of the knee, though this is a stylistic choice, this isn't exactly criticism
before talking about the manip i think it's worth saying that manipulating uke in any fashion outside of directly with the tori (hacking speed, hacking dms, or holding/moving his character) is generally frowned upon by the ukebash community due to it being a bit of a copout, as it can greatly reduce the difficulty of whatever you're trying to do. I'm only speaking specifically on holding uke at several occasions, nothing else
being able to lift uke from a position like that is very difficult, so i applaud you for that. however, I'm sure you noticed yourself how difficult it was to naturally continue a manip from this position considering you're left in the air for a huge chunk of time with no momentum. this is why i usually recommend starting manips already positioned on the floor, or using uke's body as a means of returning to the floor
at about 790 you can see that your right hip is already fully extended before the lift, greatly reducing the potential power you could have had from this point, you compensated with your left, but this forced you to "shovel" uke into the air, breaking away abruptly from the rest of the replay, which has shown a strong understanding of spins and flow
punching uke's hand was a good choice, however it could have been better set up. planting your foot flat on the floor would have allowed you to generate much more rotational momentum, reducing how far he would actually travel. this would also give you the opportunity to kick his other hand when it spins around much more reliably
kicking the legs i think was fine, though i would recommend kicking uke's legs from the side to avoid going between, because more often than not kicking between his legs is very disadvantageous if you really wanna make a cool spinny manip. i think the part after is generally fine but a bit twitchy, and raising only one arm would have looked much better in my opinion, makes the manip look a bit more "effortless" for the tori
the leg lift at 521 is certainly cool, but since you're in the air it's difficult to really make him rotate in that position, but it looks cool nonetheless lol
the first kick is actually pretty impressive considering the actual lack of reliance on grabs at that section, cool boomhit
the second one you hold uke for some reason, actually reducing the amount of dms you could get with the hit, putting you from 5 to 4 (6 to 5 counting the knee dm). i can't even really reason why you decided to hold him there in the first place lol, people don't like it anyway tho
tl;dr: generally the replay is pretty nice for someone who doesn't ukebash as frequently as others, good job. however, you should try to consider uke's position as well as yours, and try to compensate as best you can for both you and uke without directly sacrificing one or the other, a balance if you will. dms are fine but you shouldn't adjust uke's joints at all after dming him unless there's a legitimately creative reason for such, as people mostly frown upon it (as it's technically cheating lol)
