Thanks!
Improve your art skills by drawing anything you can get your hands on. Get a piece of fruit. Draw it. Don't like how it turned out? Draw it again. Then draw it a third time for good measure. The first sketch is actually good. You have curves down. It's a lot more thorough than what I feel most people think they're capable of. The biggest suggestion is confidence. It may not seem like much even good artists have confidence issues, and overcoming your fear of failure and experimenting is the biggest step.
Drawing is just one aspect of art.
I'll just copy and paste what Ed Catmull of Pixar said before:
Ed Catmull, President of Pixar and Disney Animation Studios [on what skills will be valuable for artists of the upcoming century]
"Fundamental art and science skills: drawing, color, composition, lighting, study of motion. Every studio encounters people who think they can become an artist without developing those skills. Wrong."
Because you're lacking in one area does not mean you're not in one, or two, or even three areas.
