First piece of advice: make yourself a goal to draw at least once a day. Maybe try to achieve something, like drawing a character of your own of a species you haven't done before. Something simple, but not too simple. You want to have fun while drawing, so don't feel like you are forcing yourself, but rather these moments are an opportunity to better yourself. That will go a long way towards getting better! :3

Second piece of advice: use references of all kinds. Study movies and cartoons, watch how they do things, pause if something catches your fancy. Look at people around you. You can catch some interesting poses that way.

Third piece of advice: look at real, simple objects like cubes and spheres, and observe how they appear at different angles! That way you'll get a good grasp at perspective. Don't hesitate to attempt reproducing said perspectives on paper!

Fourth piece of advice: if you draw on paper, get a pencil, possibly a 2B or 4B at first. Get a decent paper pad. And draw with thicker lines than a mechanical pencil xD

Fifth piece of advice: try to draw big, but also practice details. Even if it's making really small U shapes like scales in the middle of nowhere, it will help you get better in this department. Same for drawing as a whole, and possibly to harness proportions better.

Sixth piece of advice: find on the Internet proportions of different species (the big lines at first, then go with more details), including humans. It always helps to know where to place things~

Seventh piece of advice: go on streaming websites and watch other artists, and ask them questions too! The wider your view on art, the better to develop style, good practices, and get cool advice only experience can give you. Plus, they draw cool stuff, and there's music too! (Picarto is one of those websites most artists seem to go on nowadays)

Eight piece of advice: don't hesitate to show your work to others! A plus if they are complete strangers (maybe show to other students at school/college, or a neighbor). Friends and especially family might honey-up their answers and opinions, but seeking for good criticism and receive such criticism is one way to quickly know what definitely needs reworking in your drawings.

Ninth piece of advice: expect this to take a long time in months or years before you get really good at drawing. Some gets there faster than others, but you'll only know then if you are one of those or not. Reflect back on your past work, and look how horrible it was before compared to now. And later on, you'll find your previously best work horrible as well, while your new work becomes wonderful. The more you practice, the better you become. Maybe try redrawing one of your past works! Some artists do that sometimes~

Tenth piece of advice: reflect back on your mistakes. You like writing, so make notes of what can be improved or worked on. Don't be afraid of drawing the same thing a lot of times just to get it down (i.e. Drawing hands >w<).

Besides practice each day, have fun! The more fun you have while drawing, the more likely you'll want to continue drawing! Don't be scared of trying new stuff too. You are bound to mess up the first time (unless you are already getting the hang of it, in which case kudos to you!)~

And I think that's it. Oh and having art classes with a professional is working wonders! Good luck in your drawing endeavors!
