*Sniff.. I also feel the same as with you. Like you i also want to become a cartoonist someday. My dream job is to become an animator! hehe..
What the cartoonists do? Of course to draw, draw, and draw! Hehe just kidding. If you want to become a cartoonist someday, you must know how to draw very well.. esp. figures! Like me, i am fond of drawing anime characters! And i’m trying to perfect my body figure drawings.
If you want to become a cartoonist for a comic book, you must know what ability you are skilled of.., whether in sketching, inking or coloring..
So, if you really want to have a career in drawing, better practice a lot!
