Haha I don't remember most of my descriptions, I just added details until the rendition was acceptable.
For Liszt I think the final description was something like "A confident man with long blonde hair, wearing a chic suit, arms crossed, looking up".
For Chopin I just remember mentioning a big nose and a moribund expression.
For Bach the rendition always looked way too happy, until I added the word grumpy. By the way I never mentioned a glass of liquor, the AI just added it.
