How can i improve my artwork?

well first off you are a great artist, it will just take time to get better at what you want to get better at as of drawing, painting, coloring, etc.

It depends on how fast you want to move on with learning how to do new things though to improve your artwork.

some advice i will give you is try learning how to shade or if you know already add some shading to the artwork.

also could i have brainliest plz?

i think cheerleading is definitely a form of art. or at least it should be! not everyone has what is takes/and or the determination to become a cheerleader. it takes practice and hard work, along with being able to master a move correctly, like dancing. dancing is a form of art, and i think cheerleading is too. not everyone can dance, just like not everyone can be a cheerleader.
