Wow! Thanks for sharing this lovely content, I guess you are right with your point of view. I think asking for permission would have been a best way to do because it might be picture that you won't want to share with other people, thou this platform allow us to write or post on something we like or love but when it comes to other personal life or thing it should be ask for before doing it. Privacy is always be private and it not meant for anyone to dig into it.
I agree, and in the past I have had others ask permission and I gave it.
Would you let someone draw you? I'm thinking not considering you haven't added a profile picture.
