Hey there, I don't know why anyone would be upset by what you choose to post about - steemit is anticencorship so the worst that would happen is no one vote if they aren't interested, but I find that highly unlikely.
People tend to be attracted to those that have a passion for what they write about, I reckon do what you love - there is a massive art community here on steemit that is really well supported, jump in and give it a go you never know it could be a success.
Anyways good luck and keep at it :)
Hi @Krystle Thank you for the encouragement ::))
