@artizm, you didn't do anything wrong. It's not a fraud to find inspiration in other artists' works, that's happening all the time and it's part of the creative process. People like this self-proclaimed "plagiarism-expert" has no authority whatsoever to judge or patronize artists or enthusiasts. It's a parasite, incapable creating anything by herself. Consequently she found her niche to bully other people for "fraud". It's a pitiful individual lacking any sense of honour or decency.
I've seen her actions in the past on Steemit. Unfortunately some of the old parasites moved over to Hive as well.
Just keep painting whatever you want, don't pay attention to this idiot!
