At your playtime and consistency of play, you realistically shouldn't even be touching 190+ streams yet since you'll develop bad habits at this point. My suggestion to you is to first and foremost, nail down your consistency aspects. Start with always positioning your tablet the same, keeping your pen grip the same, angling your keyboard the same etc. Make it an identical setup every time. After that, Juuuuuuuul suggested low AR and lower bpm for finger control which is an excellent idea and start. Play maps that you probably feel are "too easy". At your time, "too easy" means maps you're probably getting 93-96 on and aim to push those up to 98s-99s. From there, move onto playing diverse types of maps and figure out what your weak points are
