I like to collect the feedback of my clients and use reviews from previous commissioners to promote my work on my website/carrd, see examples here: https://annikath-art.carrd.co/#gallery 

If you would like to write a short review about how your commission went that I may use on my website, I would greatly appreciate it! Please keep it brief so others can read it easily and include what information you think is most useful to other clients. By submitting your review here you agree that I may use your review for promotional purposes and edit it to fit my format or correct spelling mistakes for you.

If you would like to give me feedback anonymously about what you think I should work on, change or improve feel free to do so as well. I will not know who the feedback is from, unless you specify it below.
