Support and good ways to practice?

[GoingMental]

yo! Brand new here. I just have a question for all the other composers out there  I've been learning production/composition thru a private tutor for the past year now, and I'm going to college for composition in the fall. Something I deal with whenever I'm trying to make music is that I get in my own head really easily, making it difficult to feel like what I make is good or if what I'm doing is worthwhile. Practicing is another thing that I get really self conscious about. My way of practicing is transcribing songs (not necessarily all VGM) into ableton's arrangement view and trying to recreate them verbatim through MIDI, piano roll, etc. i worry that this isn't a great way to learn composition for the future and i just need some words of encouragement so i can feel good about where im headed.

Others may think differently and I'm a complete amateur myself so ymmv. But, my favorite method of practice is to take an already made midi file from a game (usually I extract it myself), import it into the DAW and try to recreate it. This let's me practice the ins and outs of the DAW, how to get things to sound less robotic, and instrument balance. The next phase is I try to add my own flavors to it. That's where I can expand my creativity. 

Again though, thats my method. You are probably way beyond that with a tutor and going to school for it and all.
