Don't know how easy it is to make it as a comic artist, but I would assume that for the majority its quite difficult, but I think its possible to make your own comic or animation movie and make it a success, even if you are not producing high quality graphic material etc. If you just have a good idea and a bit of luck by getting noticed and so forth. For instant South park - this is the first episode First episode they definitely didn't.make it due to there artist skills :D or if you look at the comic called Maus which as far as i know is also quite succesful for it storytelling. Another example is the guy that wrote "The martian" this is from Wiki:

**Andy Weir, the son of a particle physicist, has a background in computer science. He began writing the book in 2009, researching related material so that it would be as realistic as possible and based on existing technology.[8] Weir studied orbital mechanics, astronomy, and the history of manned spaceflight.[9] He said he knows the exact date of each day in the book.[10] He specifically avoided physically describing the characters when not necessary for the plot.[11]

Having been rebuffed by literary agents when trying to get prior books published, Weir decided to put the book online in serial format one chapter at a time for free at his website. At the request of fans, he made an Amazon Kindle version available at 99 cents (the minimum allowable price he could set).[8] The Kindle edition rose to the top of Amazon's list of best-selling science-fiction titles, where it sold 35,000 copies in three months, more than had been previously downloaded free.[8][10] This garnered the attention of publishers: Podium Publishing, an audiobook publisher, signed for the audiobook rights in January 2013. Weir sold the print rights to Crown in March 2013 for over US$100,000.[8]

The book debuted on the New York Times Best Seller list on March 2, 2014, in the hardcover fiction category at twelfth position.[12]**

Not that I know anything about your skills or story etc. But there are some people that make it out there, turning there stuff into huge successes, maybe you are the next one, who knows? :D

But I think as some others have already suggested that you should do it as a hobby unless you have the resources to do it full time with the risk of it not being a success, if the stuff you make is good someone will probably notice you at some point...anyway just my personal opinion.
