- Work on conceptualizing your ideas on the canvas better
- Use of light
including shadows (you're lying if you think they look good that way, someone noticed a very valid flaw in your work and you fucking flipped him the bird, and don't compare your work to Picasso - he was abstract in his later work, but if you knew anything about the guy you'd know he was a brilliant life painter.
- Weight of line ( using bolder lines for darker areas, finer lines for lighter areas)
- Try using less...BOLD colours.
Always strive to improve, never be satisfied with what you produce, KNOW you can do better and eventually your stuff will look amazing. Seriously, give it a go.
