On top of all the stuff I said earlier, there are just a few things I'd like to add:
- Ragna's ground bloodscythe is positive on block, so you really don't want to be mashing once you've blocked it, especially given the fact that his normals far out range yours (Hazama 3C could contest but its not a good idea to use that after having blocked BS). The push back on ground bloodscythe positions Ragna in the best way to get a 5B/5C CH should you be mashing buttons. At that range your normals will most whiff.
- There was one thing you did in one of the videos (can't remember which one) where you used an air chain CH followup into Houtenjin, which was pretty good hit confirm. Overall though, I think you could work a bit on your hit confirm. There are several times where I witnessed you throwing 2B in combos when you could have gone straight into 5B > 3C for example. There were also times where you got a 2B hit but didn't confirm a combo and instead went into 214D~A.
- Personally, I think your chain movements could be a little more ambiguous and seem to be a bit predictable. For example, you got anti-aired quite a few times against that amane (tbh you should have actually been anti-aired more, if the amane was more competent). More B/C chain followups are good to use once in a while. Personally my favourite movement is j.4D~immediate D followup, which can cross up at the right distance. Use varying chain movements to throw the opponent off and be less predictable. Also when you throw a chain out, don't feel as though you have an obligation to use a follow up. Try and use mind games and make your opponent guess when you'll approach.
- Lastly, I think you could do a bit more to catch your opponent when pressuring them. You aren't really making use of Hazama all of hazama's tools (frametraps, command grab, tick throws). Your main mixup seems to come from stance overheads and lows, which is not reliable at all. It is good to use that once in a while, but I just feel as though you could just be doing more to pressure your opponent. 2C jump cancels are pretty good too.
