I really enjoyed this as a concept. Thank you for including a range of people in your customer models too, it made me so happy to see :D
The controls for sizing etc were easy to use and I liked that you can add as much as you like to the mask (as long as you meet the requirements). There were a couple of prompts I missed that didn't make much sense though e.g. the stick didn't count as crooked, the pair of stones/bubbles didn't count as grey.
