Aaa, that's a very flattering question, but unfortunately it's not an easy one to answer because there's so much to say about it! My first tip is to figure out what you want to draw, and then practice drawing that. Use photo references and break down the subject(s) you want to draw into simple shapes. Draw from life or photos where you can, especially when you're just getting started. It helps you build up a good memory for what you're going to draw and along the way you learn how to break down real-life objects into 2D representations. dA user Tamberella has a really great
How to Draw ANYTHING tutorial that's a good starting point whether you're a complete beginner or a seasoned pro. There are also lots of great tutorials here and all across the world wide web - if you want to draw anything from spiders to human hands, if you google "how to draw X" you'll probably find some good advice. While it's biased towards my own needs, my
Tutorials Favorites folder has a lot of good material in it, too.
My other tips are mostly mental - try not to get discouraged if your art doesn't look exactly the way you imagined it. Remember that you're always going to see more flaws than other people will, because you know your art better than anyone else. No matter what you draw, no matter how "good" or "bad" it is, you've created it, and that's something to be proud of!
Best of luck on your artistic journey!
