I really enjoyed listening to this. I love the style you chose and the instruments you used. In addition, I loved the way you set-up and used the eagle metaphor in verse 1. Then there is that chorus...
I'm guessing that just about 100% of adults on earth can relate to thinking about what should have been said and fretting about the past the future. As I see it, that's really skillful lyric writing.
Your work with Synth V is excellent. When I consider the facts that your first language is Finnish (a syllable-timed language), and that you create songs in English (a stress-timed language), you really do an exceptional job. I tip my metaphorical hat to you. As you would know, stress-timed languages require knowing about which syllables and words are slightly longer than other syllables and words. Moreover, to get Synth V to produce vocals that sound realistic, the correct placement of syllables/words not only relies on putting them on notes of suitable length but also notes that are suitably placed within the bar on the appropriate musical beats and between beats.
You've got a lot to be proud of with this song.
You also convinced me that I need NOA Hex! (You must have a heap of vocaloid voices.)
Happy new year to you
