>>5699293To be technically good is to be able to convey your vision on medium in a way that is both pleasing and accurate.
Now this generally goes for anything non abstract. Illustrations, comics, paintings, cartoons, heavily stylized and more semi realistic.
You have to have a solid understanding of perspective to make your scene convincing, a solid understanding of anatomy and how the body works in general for believable characters, you have to know how color hues shift with light and shadow etc.
Even the most simplistic cartoons reveal the artists technical knowledge. There are cartoonists I've seen that I just knew could paint or draw realistically as well just by looking at their cartoons. It was conveyed by their confidence and by how they demonstrated a consistency in their system. Little things.
That said it helps a lot to know, beforehand, what kind of style you are going for and hone in on that goal.
Generally though when you've reached your set goal there's always a bigger goal becoming just above the horizon.
It can go like this: You become proficient in characters but when you try to place them in an environment you find you can't. Then you start studying environments and after a while you can put it to use only to find that you might need to work on composition or more world building.
A good artist acknowledges his weaknesses so he can work on them.
This is how he improves.
You always have the people yelling "but it's just their/my style!!1" yet they are not aware of their own self deception and ignorance. Lots of egotards in art. It takes honesty with the self. You have to take a lot of L's in order to get that first win. A very awarding path none the less.
