All are great comments. I was apprehensive about giving any "constructive" criticism because of a previous post on another forum. I said what I liked about the artwork and said what it was lacking and what would improve it. All I received was angry comments.
The only comment was basically what Hermance and Zee explained. The rest of it I liked. The key word is "constructive." Gives the artist something to work with, not "I don't like it" or "it's just kinda weird." More intelligent, positive, honest feedback is helpful.
