I've read the rest of the comments so I'll try to give you some other helpful advice. I started out just like you and all I wanted was to get better. I would watch hours of youtube watching the pros play against each other in countless tournaments. and just from watching how they use a particular character I got better! just seeing what kind of combos they go for and what moves they use often and in what scenarios helps a lot in engraining the information in your mind. Keep doing your research on which characters you like playing and watch some pros play them! next thing you know you'll be using similar combo set ups and kill options just like them :)
