Seen others use it and been asked if I have considered it, and can't lie that I haven't, but question is if I started one, what to do?

Would sketches and images really be enough? Sort of different sketches of ideas I have to sketching of known characters?

From what I could tell, comics might be the best selling point, with with limited to none ability to tell a story, would that be bad thing to do?

And was thinking a selling point was muscle up cartoon female characters and stories of my own characters.

But as it is now, haven't decided yet.
Just toying with the idea. What do people think?
