Nice. I find that the hardest thing with him is just getting into a flow where you're comfortable with mix-ups in combat. Because those mid punches are so tempting xD
Id say the best thing to do with akira is to avoid mid punches use setups like SS~K 66P 3H+KP~2or8 and usally at this point someone trys to counter so i use his 16T~H~P for akira side step is ur best friend and i recommend using his 4T 16T and 214T set up throws
Kinda what brute said, Getting comfortable is one of them.
Nothing really wrong with the mid punches to be honest, as long as you don't make it too obvious. You don't necessarily have to play the stun game with Akira because his launchers and damage is really good overall. Really for the dedicated. Take advantage off the traps and setups and gain character knowledge on the opponent to savor it up.
