The problem is to accaully to what the score tells you, and not "Kind of what it says". Ofc, sometimes you need a bit of rubato and timing and such, but you'll get there
Do what the composer writes in the score, and you'll be fine

For me there is always a line you have to walk with composed pieces. They have a general path that everyone has to take to play the piece well, however there are certain points which we may put our own ideas in, perhaps over exaggerate dynamics, tempo, note quality, add notes, detach notes etc. To me it is what makes playing classical music somewhat organic and different every time you play. Yes you must present a standard interpretation but at the same time you must be able to craft your voice around the music.
Record yourself, and be very critical.
