The zoom distance should really be increased. Zooming in works fine and shows high details on the character.

For the sound, I have to admit I never heard an anoying sound while hovering. I have every soundbar on full with my 5.1 speakers.

The sound in the game is beautiful. I really like the different themes and it is awesome that the music for the character specific instrument plays exactly the music in the character screen while you test it ^^
