I don't see this as a negative comment - it's clearly made by someone who appreciates the huge amount of effort required to make a piece of photo-realistic art and is trying to express their appreciation in a funny way by use of sarcasm.
It's a shame the artist decided to stop making art but it's not even explicitly stated in the article that he was affected by negative online attention. He may not have read the comments or he may have stopped because of his illness regardless of the comments.
