I find myself struggling in terms of drawing: my poor choices for making art have caught up with me. My tendancy to get bored after inking a face and torso. My general avoidance of color. My 3/4s standing positions. My anime tier samefaces. Doing all of these for years has left my ability very stale.
Don't be like me. You'll regret it. And you know what, I remember hearing the same thing too.
The best I can really do is push past the boundries I've unintentionally created for myself. Refusing to get bored. Planning, and applying color (as opposed to just slapping it on, semi-randomly, like a neanderthal.) Drawing different poses over and over again till I get it right. And working on giving each of my characters actual facial features.
