u/Supernova_not_taken

I started playing this game around late last year and I've gotten to around 5k elo with 240 hours. (I'm on OCE servers). I feel like I am playing pretty well but I stand no chance against people above my elo range. What routines/things I should look out for do I do to improve at the game?

I'm not sure if this helps but here is my Leetify profile and some demos.
