Practice, practice, practice.....respecting brush time....
I'm going to post to Yahoo's Everydaymatter's art group, of which I have been a member for some time now. The groups is always generous with positive feedback. I'm thinking .... lack of aerial perspective, improper shading (depicting rocks is a PAIN !!), and overall coloration are why I don't like it.
It was still fun to do because painting with Amy is always fun !!
