Reddit mentions of Fantasy Art Drawing Skills

There's one thing I always recommend for this: Drawing for Fantasy Artists. I know it says fantasy, but it's helpful in general. It's what taught me how to do complex stuff like shading fur and bark, building scenes dramatically, or just doing outlines. That aside, you should start by copying lots of styles you like and learning to draw those, then you'll slowly start forming your own. It'll happen quite naturally. Best of luck!
