Miss Nancy brings up a good, solid point:  What is your target audience?

If you are self publishing, and you do not care about profit, then you do not (perspectively) need as high of quality in the picuteures department.  Hopefully your story will carry you.

If you are looking to compete with "the big boys", then your art, as well as your story matter.

If you are using a Poser-to-Photoshop work flow and looking to compete with the big boys, PM me.  I will answer any questions you have and/or direct you to the most helpful online tutoriais.

I completely believe in an artists freedom to tell a story, but I insist that quality will be what differentiats you to begin with.

The first and most imporatant thing you will have to learn is that POSER is a bad word amoung those who work in 3D art. 

You may have wondered why you do not see Poser art in conic pages.  The truth is, the freedom of image takes a lot of work and POSER images themselves will be flat out denied by all but pose publishers (Renderotica excepted).

I did see a Poser based comic a few months back in Heavy Metal but they did so much post work and base painting that the only things recognixable were the V3 eyes.

In anycase, PM with any questions, I will be glad to point you in the right direction.
