1) Don't feel around for forms when you sketch. Imagination drawing should be observational drawing, based on a visualized image/scene.
2) Slow down your lines and markmaking. Speed up your overall process/time devoted to a piece. Fail fast and realize quickly when something isn't working. Don't get into a groove that will get you nowhere.
3) Idea > form > color/light > texture. Design choices between each step; iterate.
4) Do actual studies instead of just blindly sketching all the time.
5) Plan portfolio pieces (and even sketches), don't just hope a random drawing is amazing. Work on visualization.
6) Most of the time spent is loose planning. When possible, put down final strikes first.
7) Try oil painting so you can realize how useful digital painting is.
