Beautiful picture!
Man, I wish I was that good at drawing stuff like that....
Thanks!

The reality is just practicing forever. I've been drawing since before I could write my name properly. The only way to get gud at something is to do the thing. Over and over and over again. I think lots of people are more capable of drawing than they think, they just haven't invested the time into it.
Even today I'm constantly going back to the basics. >_> To draw the trees and get the sizes right for this picture I ended up taking a bunch of drill bits and scattering them upright on a flat book and then used some tiny objects to represent my person and the skeleton. It was like a diorama of drill bits. Then I dropped my head down to level with the flat surface of the book and pretended the drill bits were trees to get the perspective mostly right. I tried to draw this like six times before this without that direct reference and it was just terrible. So it's always good to remember that everyone is just kind of muddling through it.
