The fusion of acoustic melodies and modern instruments/mixing techniques is extremely fascinating, it shouldn't work as well as it does (especially that WICKED drop) and yet it totally does. The whole thing just sounds so damn clean and punchy. As I've written this whole comment out I've probably replayed this about a dozen times because it just worms its way into your brain and commands your attention.
I think it's really easy to listen to works from other musicians in your sphere and get discouraged. My theory is, much like you've discovered, that it has a lot to do with specializing. Music, and the tools used to make it, have diversified a lot in just the past decade or two. It's easier than ever now to find new stimuli in places you didn't even know existed, and in those places you'll find people who have been practicing just like you have, getting amazingly good at their own thing and iterating off a completely different set of experiences and influences. You could have a person who knows EXACTLY as much about music composition and theory as you do, but if their specialty is, say, piano solos, then you would probably still feel inferior by comparison because it may not be a field you have much familiarity with. They would feel the exact same about you, for the exact same reason.
You hit the nail on the head though about why you wrote this song. You are an individual built of a completely unique mix of influences and experiences. We adapt and evolve as we take on new stimuli, but we are still wholly unique in how we express these facets of ourselves. Other people may do *their* styles of music better, but nobody does your style better than you do.
