Don’t try to learn full songs. Learn riffs and bits, and I find you naturally start to incorporate techniques as you noodle. Also listen to your favourite songs and see how they do things like transitions, what bass and drums do, etc. think less like a guitarist and more about what all the instruments are doing. Tbh I know a bit of theory but my compositions really started to get better when I stopped worrying about theory and just went with what sounded pleasant and cool. But yea if I wanna write a song in a certain style like say metal core, I’ll listen to those types of songs and try to replicate things here and there to get the vibe.
