Hi. I see you are new on Hive. Some people like to see confirmation that the art is really yours. Maybe sign it with your Hive username. You could also do a post with some proof of ID. That can be a selfie or video. You can also link from other social accounts. When money is involved people are wary of imitators and we do get some.
Have fun.
Thanks a lot sir.. this is useful for me 😊😍😍
