hey you could add me to play, I am not very good but looking to improve too!

Add me me to

Learn your characters entire kit in training while also using the customization option to practice particular areas of combat you wan't to improve on. Repetition of basic strings over and over until they're memory reflex, then move onto combos. There's a combo challenge for each character that will give you an idea of how to combo while walking you through them... start small then go big, big combos aren't always going to be achievable online so focus on mixup until you see your opponent has a weakness defending a particular string then exploit it with big, then move onto spacing and control.
For accelerated learning after memorizing basic move-set, copy a veterans combos and approach to matches from some of their posted content to get an idea of what flows together. I believe ninjakilla starts most of his video showcasing some nasty combos so maybe reference him. Big combos aren't necessary to achieve a win online in the slightest, most people go online as a one-trick pony, figure out their flow then learn and adapt from it and you'll win, or they'll lag switch out. Don't skip players with large win/loss unless you just can't keep up, that's where you'll get the most experience, if you face lower tier players non-stop you'll become complacent with facing the same strategy. When you're able to beat the cpu on max difficulty you'll be better than about 78% of the player-base! There's more to it than just what's mentioned here but you'll learn those things as you put more time into perfecting your gameplay.
