Hi there! Your artwork is beautiful, but I'm actually here because I wanted to warn you that I think someone is selling your work on a different site without your permission. (I don't use dA but I couldn't find an email address to contact you, I hope this message reaches you...) I don't speak Italian, I hope you can understand my message!
This person (looks like from China) is selling your Alice in Wonderland, "All Mad" on a tote: https://www.etsy.com/listing/1043040893/alice-in-wonderland-tote?ref=user_profile&pro=1&frs=1 They are also selling several other of your disney designs on totes too (Elsa, Cinderella, Aurora).
If you gave them permission or this is actually you then that's fine, but I am doubting it since it's shipping from China and their other designs are from different artists. You might want to see if you can report them.
Also you should try selling your designs on Etsy yourself, I think you'd get a lot of sales there and would minimize art thieves. I bought some of your shirts off pampling, but almost decided not to even though I wanted to buy some of your designs, just because sites like pampling/onceuponatee are unfamiliar sites to me (and I think most people). Etsy is a really well known site and has a huge userbase ,and for a lot of people it's where they check first when they want to buy people gifts. Just a recommendation!
