Animatorfag here, OP
If you're 22, you still have time, I'm not super good or anything, but you have to commit to your dream fully, and practice a lot as well, here is some good advice.
>Practice life drawing
The most important thing, if you can't go to a real life drawing session, there are several sites where you can get a lot of pictures, models and 3D models to draw, do this, with time limits, do not concern yourself about getting the details but rather with capturing the pose, action and proportions, and learn how joints, muscles and necks work as you draw. If you get good at this, your overall art will improve.
>Practice EVERY.SINGLE.DAY
Do the above, while also working on your stuff a bit, see the life drawing as "grinding" or "exercise" and doing your stuff as the "fun part", but I hope you enjoy life drawing a lot.
>Learn perspective and composition
There are many tutorials on this, but practice these with basic shapes like cubes, prisms and spheres, and then apply them to compositions, multiple characters, the golden ratio, foreground and backgrounds, this is more important if you wanna learn how to do backgrounds too, but will also help A LOT.
>Look for inspiration
Look at how other famous character designers simplify the designs, I don't recommend looking at complicated things like detailed manga artists, but rather animation designs, with western look at Shane Glines and Bruce Timm, while look at Toriyama or early Sugimori for the east for example, see what they do and how they draw things like arms, proportions and silhouettes.
>Don't be afraid of criticism
Fuck those gamefaqs guys, but constructive criticism is VERY important, specially who and how they say it, ask for experienced artists but also the opinion of random people will help too, accept and learn from your mistakes.
>Learn some drawing software
Self explanatory, but I reccomend Sai and Photoshop.
