I know I'd be excited to hear what you've got going on in the music works. As for the repetition of the theme, one of the musical realizations ive had over time is that most notable musicians and acts find a niche that works and stay in it. I think a lot of musicians feel the need to always play the most varied repertoire and not revisit the same ideas over and over again, but the famous musicians you can recognize instantly by hearing them do just that. Good taste doesn't necessarily preclude dressing up the same things over and over again.
I wasn't going to share anything until I felt the collection was done, but here's a temporary private link to my most recently complete track: https://clyp.it/5jjzt00j?token=7fb9e741156215bdf16c0cf416a070a6 I like your take on revisiting ideas. A composer who springs to mind is Steve Reich and his contrapuntal works. From a macro perspective they can sound quite similar, but once you get into the piece there's lots of new things to hear. But yeah, trying to make something completely different for each piece is something I've struggled with for years and it's only in the last 12 months that I've started to hone in on sound of my own.
