I agree with Solar's assessment.
I think you just need to focus on basics right now. Stein formation and combos, as Solar said, but also just stuff like when to block, and when to throw out certain pokes or steins. Also, don't wait until the opponent is right on top of you to do the command laser. Some things will just come with experience, like when to burst. For example, your first burst in that match against Noel wasn't a good time to burst, the combo was basically over and your opponent wasn't going to get any more damage, however, your second burst was much better.
I also recommend that if you're playing online, try player matches and join a room. Online is fine and all, better than nothing, but ranked is too much noise. Too many styles, too many different opponents doing crazy shizz, too much adjusting to varying levels of lag and skill, etc. Also, if you play people on Dustloop, they'll be willing to help you out and tell you what you did wrong, I bet. :3
