I think, SMG....
that we ALL catch a bit of the "fire" when we're composing.
Right now, I have easily twice as much music theory and knowledge as I did 4 years ago - resulting from studying and practicing a lot.
BUT I feel like I actually managed to *lose* that spark that made my tunes simple, catchy, fun melodies because now my mind wants to tend towards music theory-based songwriting choices rather than trying to convey a mood or bring some emotion or thought-pattern forth from the listener. It's become more of a technical pursuit in writing things with the densest, jazziest chords and fullest instrumentations, rather than aiming for the simplicity than can come with a good set of chords and a quality melody with good lyrics.
I guess my point is that I feel like I personally am just on a small stop on the way to creating much greater stuff than what I could do 4 or 5 years ago. And just to think of where I might be able to end up in another 5 years of work in the same direction.
Not that my experience applies to what you're doing. I think if you're enjoying what you're doing, just keep truckin'. I
personally don't know if I'm hearing "amazing", groundbreaking music being created, but I can definitely say that what you're making is
you. That it's not necessarily likely someone is going to make the exact same melodic or harmonic choices as you, that no others will likely use the same synths/samples that you choose. Keep developing your style and production skills, don't necessarily settle on assuming that you've already reached the divine level of songwriting of the "masters"... there's
always more to learn when it comes to music and sound!
