You need to hit confirm the f24 overhead and b14 low combo starters. The bo swing combo ender is really unsafe on block despite the pushback, especially against a cassie player whose punishes cover a lot of ground. There are also some more optimal combos that are just as easy but do more damage so look into that.
Raw divekick which you did at the end is also unsafe, so whenever you go for a hard read like that, make sure to meter burn it. The jump back divekick always gets people, but just make sure you're safe. I think that was the main issue. As long as you don't throw out random specials, you'll get a lot better.
Be more patient and don't jump and cross over so much. This guy didn't know how to deal with it but you might get blown up for it against other players. Be more patient and punish them with your range. Use Up1 or just standing 1,1 for anti-airs that can convert into some damaging combos.
Nice Bo Flame! So close to a brutality
