Hey Seyfer,
watched your clips. There are a lot of points when you seem to be messing around, going into meditation randomly right in front of your opponent etc. Usually a bad idea practically but it can be fun, I do it also when not playing seriously.
Just a couple of basic comments since I'm not qualified to give top level advice. Many times when you blocked a string from your opponent that left you crouching you used WR B. This move isn't great. It's linear and high. Since your opponent was giving you the initiative, you should have done a mixup. From crouch, a very easy mixup to do is FC3K/4KB. In general I would have used FC3K more often because the major downside of that move is that its very punishable on block, but your opponent wasn't punishing a lot of things. As opposed to using 6K2K to mixup; this is a bad idea because the opponent sees the mid first and has plenty of time to block the low. Also 6K2K is disadvantage even on hit (whereas FC3K is knockdown on hit). I think using FC3K alone would make a big difference and let you damage him much faster. You used step and grab btw really well in the second video. However using FC3K makes you more of a threat from range.
Another really bad idea (although he didn't make you pay for it) is throwing out 3AB when you have advantage. 3AB is not a combo, it only combos on counterhit. So, if your opponent is just ducking and you 3AB him, you still won't launch him in the air. 3AB when blocked allows him to hit you with pretty much any move he wants for free. 3AB you should use only if you think you can get it on counterhit. If you don't think he's going to attack and you want to try to launch him, use 3B as at least that way it launches on normal hit. I wouldn't do that either though, I would use more 33B B+K. You used 33B a few times but didn't follow up, the B+K combos and is free damage. I also like 4KB as a mid more than 3B, it's somewhat unsafe but you can play a lot with when you release the B. You used 66B which is also a decent mid, slow but safe and good damage, however you shouldn't go into intimidation after with 66 so often. If it's blocked, I think that your options aren't fast enough to avoid getting launched.
Nice video though, lots of nice GI and step and way to make use of SDGF K:K!
