Hi Sullykin, I'm Evan, a songwriter and pianist/guitarist in Tennessee. A clockwork bird and a nightingale is a beautiful pairing, and I'd love to help those melodies sound like a person is playing them. Most of my instrumental work is soft, quiet piano and fingerpicked guitar. The Apricity creator pack is a good place to start listening: https://evanhballard.bandcamp.com/album/apricity-instrumentals-creator-pack (more at https://evanhballard.bandcamp.com). I'd be glad to do the one-piece paid trial. I'd keep your melody's identity and rework the voicing, dynamics, and phrasing, then send back MIDI plus a rendered WAV. Rate: $75 flat for the trial piece, and I can start this week. Fun fact: my soundtrack album The Markov Seduction is an anagram of "The Movie Soundtrack."
