Fundamentals. Spacing. Execution.
You do not have a grasp on these in 100 matches, i promise you.
If you want tangible directive advice id say to look up your little bread n butter links like crMK into Hadouken and shit and drill those during matches.
Also learn what your character's punishing options are for when your opponents inevitably leave themselves wide open by missing a shortu or wake up super/ultra/whatever conematic move
