Drawing is a skill. If you've ever tried to draw something by copying it, and yours comes out all wonky and strange, it's not because you "can't draw" or don't have talent. It's because it's a skill and you literally don't yet have your hand trained to perform how you want it to.

It comes, with training and with time. It comes with practice and doing it regularly. It's like cooking, it's like blacksmithing, it's like anything. It's a physical skill that requires a specific muscle set and type of coordination between your brain and your hand.

don't let it discourage you. Don't say "Oh I must not be able to do it". Anyone can draw. You can do it! But like building any muscle, it takes time. You won't be able to draw everything you want at once, even if you can see it super clearly in your head.

And honestly, it doesn't even take like a regimen of strict dedication. Are you pretty decent or even really good at video games? How did that happen? chances are it happened while you were just enjoying the process of playing games. Same process. Enjoy the journey.
