I’ll agree with previous statements that your throwing out QCF+K a bit to much. It’s good to throw out once in a blue moon, especially if you anticipate someone jumping away, but even then, don’t over do it.
First of all, use more far standing fierce. It’s a pretty good mid-range poke to throw out every once and awhile. After watching the last sean v sean vid I noticed that not once was cl.HK thrown out. Your missing out on sean’s best meaty as well as a move that makes hit-confirming easy… which leads to the next topic of hit-confirming. Wake-up supers are fine at lower level play, but the risk of wasting a super by just throwing it out and hoping your opponent sticks out a meaty is bad… especially when your using SA3. That’s alot of meter to blow if it whiffs, as well as a big punishment afterwards. Try to learn hit confirming.
~Use close standing roundhouse and input two QCFs. In the time frame of the move, you should be able to tell if it hit or got blocked. If it hits, hit any punch and out pops a super.
~ cr.LK x 2 is THE best combo to practice hit confirming off. It will help prepare you if you decide to broaden you horizons to other character as well. (cr.LK x 2 xx corkscrew blow OR shippu OR messatsu gouhadou, etc.)
As far as more sean specific… meh. I only mess around with him on occaision. I WILL say that I enjoy doing dash under --> strong xx roundhouse chain as an anti-air. Oh! and rely less on his headbutt. (fwd. fierce) I think it’s the slowest command overhead in the game and easy to block on reaction by a more seasoned player. The more experienced people you play, the more youll find that headbutt and his flip kick getting blocked, or in the case of the flip kick, more likely parried. Hope this helped.
