Don't take this as anything more than CnC. Just figured I might be able to help you out a little. I'll CnC your two recent replays one after the other, and give you a little insight.
NowThisIsEpicShit: It's apparent that you know how to boom, and that's a rather nice skill to have in terms of making a replay look good and exciting. The starter you used was rather odd and simplistic. The first kick was destructive but very stiff. Afterwards, you flailed around for awhile until you were close enough to grab Uke, in which you were in the air for a longer period of time than you could have been. When you got to the second kick, it was destructive, despite being extremely strange. You did this back-flip at frame 420 which was entirely unnecessary and wasn't done well, and the pose wasn't good either. You were either too stiff or too relaxed in the replay, which threw me off.
fl0woverdose: I was kind of expecting some flow with fl0woverdose, but it wasn't there. The starter was odd, and the jump was even weirder. The first kick could have been more powerful. The second kick actually surprised me. I don't think I've ever seen an arm and leg boom before. It was a very powerful hit. The third and fourth kicks were a little odd to me, but destructive nonetheless. It took you much too long to pose, and when you did, you fell down. You were very stiff when you were trying to get into the pose.
You need to work on style. Your movements don't have any
flow (I've provided a link for your benefit), and really you're just wobbling around until you can get closer to Uke. Practice standing on your feet, as hand standing and flailing around throughout a replay is never good. You know how to boom, so making your moves more fluid and practicing balance will make you a better replay maker. I'd recommend that you watch some of the other replay makers to get some ideas, and practice what you see to better yourself.
Happy replay making, and sorry for the wall of text. ;o
