Copying

My daughter had a friend text her a fairy holding a skull sitting in front of a tree with a large moon behind it. It is a great pic but the problem is/was she wants me to draw it for her. I do not like copying other peoples art for obvious reasons. However Edgar Degas told one of his students that, "The masters must be copied over and over again and it is only after proving yourself a good copyist that you can reasonably be permitted to draw a radish from nature." Now this drawing of the fairy is certainly not by one of the Masters, but it does raise a good debate question. When is it okay to copy some other artist's work? Here are my beliefs on it.

• Never copy another's work, no matter how trivial or unknown, if your point of doing so is for profit or fame.
• It is fine to copy another's work as long as you are doing it to either further your own art or your understanding of the original artist
• It is okay to copy another artist if you are wish to work in their style
• It is okay to copy another's work if it is for your own pleasure

That being said, I guess I will make a hard copy of her text message picture beings it falls into the criteria. I am not doing it for profit, I will not claim it as my own, and it is going to be hung on my daughter's wall for her pleasure. Guess I need to get started on it.
