Smashysmash by JessicaMDouglas
has been on dA longer than I. She was one of the artists I followed here in 2005 as Elfwood was hitting the skids. I do enjoy her paintings.
Be careful what you awaken when you sail into the ring of fire.
Steve's suggestions on how to leave a good comment...
Tell the artist what caught your eye, something your particularly liked or didn't like.
Tell the artist something you think they could have done differently or better.
Suggest an alternate title; it tells the artist what you saw in the image.
Interact with the artwork, continue its story.
Ask the artist how or why they did something.
If nothing else, even "Ooh, pretty!" or "Oh, ick!" is a lot more information than no comment at all.
