I never understood why artists are so paranoied about their art?
Any art piece can be used as an inspiration or resource as long as both parties follow fair use agreement.
If you are affraid of someone stealing your art eather don't upload it on a public website or just use a signature.
I would actually be proud of myself if someone had stolen my art-to me this means that somebody is actually interested in my art-besides if it isn't your source of funds (meaning you don't get any money out of it )I don't see the problem as long as the person doesn't claim the art as their original work.
Good example of this are motivational posters.
This quote explains my thinking: ''I don't care that they stole my idea . . I care that they don't have any of their own' -Nikola Tesla “

Please don't block me or flag my comments as spam I was just stating my opinion any person rading this can eather follow my advice or choose to ignore it-I don't care eather way.
