Let's face it... this is a relatively new thing. The thing about it is... you're going to run into opinions concerning using 3D art to illustrate your stories - novels - novellas. Those opinions will be positive and most certainly negative. I've certainly had plenty of the negatives - oh yes, let me tell you. Why the negativity? Not sure why to be honest. Because I have so many strong opinions on the why of the negatives - I'll try to bring on a few of the minor whys. First let me say, that an illustrations is just that, to give visual imagery to a story, a character an idea. Unless you have an amazing drawing talent on top of writing, you're going to have to look elsewhere for ways or means to publish your work.
