The logo that I put on my pictures cannot be removed or edited out by anyone who buys a commission from me. If a client would like it to be smaller or less noticeable then if they ask I will change it but it will be on the picture regardless. If a client is going to post the picture anywhere than I must be credited. I can also post any of the commissions I draw on any social media or create videos about or involving them unless asked otherwise. If a client asks me not to post or make a video about their commission then I won't. But if they do not tell me that they do not want it to be posted or made into a video then by default I will post it.
