Also, a note to add....I wouldn't recommend trying all of this on your own. It seems to me like your sitting in the cockpit of an airplane, and not knowing how all of the instruments work. If you try to experiment, then it may lead to disaster (literally ) You need someone who can teach you everything you must know so that you can fly that plane and tackle all of the loops and turns that come with it. And don't put all of the pressure on yourself. No one is able to accurately analyze their playing without a teacher's assistance. (Or a good one to be more specific) You will learn so much, things that you may have been completely oblivious to before. Get a good teacher, this is what will help to improve your playing.
you are only pronbably an intermediate student now...all the songs from games/movies don't help you solve any problems or learn any skills, and you haven't learnt any pieces that I would give to my beginner students to help them in anyway. You should'nt try moving on to any advanced pieces, honestly, do you know how much harder they are?Let me reccomend you a few classical pieces to work on- Schumann: Album for the young- A few of Bach's pieces from the Anna Magdalene Album- A few of the easier Kulah/Clementi/Beethoven Sonatinas
