Do you think Cartoon Design is a good job?
I can draw some cartoons, but I don't know whether Cartoon Design is a good job or not.
If you enjoy and can get a job doing it, then it's a great job, a fantastic job really since work won't seem like work and you'll feel like you're getting paid to do your hobby.
Just don't draw any of the unmentionable cartoons or some people will come after you (not me) but just read the news on this sensitive topic.
Yes, it can be a great career, but you need to plan a career path in art and drawing, get a Master degree in fine arts, and you will be on your way. There are many people out there who can draw amazingly well, but they will never make any money because they didn't go to school and earn their degree.
