Hi DusaSN,
while I do ok with art and programming, I fear my talent for music is very limited. Collaborating with a musician would be a dream for me. I am working on a free fantasy game right now involving a fairy. I will release it at Christmas for friends and family (and your friends and family too of course). 
To give you an idea I add a screenshot of my current game, but that is still far from finished. You can also check out my previous games here on Itch.io.
For the current game, music-wise, I go mostly with Tchaikovsky so far, but I am not entirely happy. Especially since I fear not everybody likes classical music like me.
Kind regards
Smurjo
