Hello again! If you're going for that undefined look, where things bleed into the bg and even prominent features (like the mouth) are only hinted at, then I suggest using more expressive colors for those pieces AND broader brush strokes.
I have to disagree with you there, I think that piece does have emotion. It was a quick thing that I did where I reached a point that I liked, which had a strange kind of subtlety. The nose isn't quite correct and the mouth isn't defined harshly on purpose, but who ever said that everything HAD to be anatomically correct and everything HAD to be defined?
