This is what I do ↓↓↓
1- pick image
2- go here https://pinetools.com/invert-image-colors (to invert the image colors)
3- go here https://www.twitchquotes.com/ascii-art-generator (to turn your inverted image into ascii art)
idk what size you need exaclty for the review but I usually set it to 28-35 for character width when I add comments on profiles.
Not perfect but it works fine, sometimes I adjust little details manually to give a desired result.
I hope this was helpful :D
