I asked people on my Twitter account as well as personal friends and family to suggest to me one article of clothing/feature that should be added on to a blank slate of a character, in which then I would proceed to combine into one final original character out of that collaborative effort. I had over 50 suggestions and this is the final result - I couldn't take every suggestion, so I picked and chose whichever ones I liked the best.
Vague suggestions such as articles of clothing were suggested by people on twitter, while the more specific characteristics such as eye shapes, hair colour, size of character, height, were suggested by personal friends.
I did not explicitly state it was a crowdsourcing project but I did say it was a collaborative project in which I took the ideas of those I enjoyed.
