Hello there! I am not that good >w<.
Hmmm. I will try to list as many as I can.
First and foremost, always remember that no artist becomes extremely good without practice. As they always say, practice makes perfect, and this helps a lot with drawing. You get a better feel of what you are doing in the longer run.
Since you are a still troubled by anatomy, don't be scared to use references! You could always use Google to search an image that you could use to check how something goes if you can't draw it from the top of your head.
You could also use guidelines, they will really help you a lot! Try to simplify things into basic shapes, then add details as you go. You'll eventually start breaking away from these, but it's really nice to put some things in perspective.
Feel free to explore and be afraid to try stuff out. Draw whenever you can, it doesn't have to be perfect, just keep drawing if it makes you happy.
Feel free to VM me whenever you like! Even if it isn't art-related things. I hope you find happiness in your drawings :D
