An experiment - what do you think?

OK last week I played around with using a wash on a picture (the apple and pitcher one). I was impressed how it worked. Well one problem I have been having with my portraits is shadows. So I thought I'd try putting in a shadow using a wash on a finished portrait. What do you think? A wash can't be used until the picture is pretty dry or else it just smears all the colors, but I'm thinking I like the effect.
