Individuality, yes. Work at developing your own 'style' and then practice, practice, practice.

I visit a site that features bad book covers. It's amazing what some authors will allow on the cover of their book. Whenever a Poser or Studio generated cover comes up it's obvious to me because it usually contains content I own. Often, they artist doesn't even bother to morph Vickie or Mike. It's also obvious to the folks who frequent the site. When a 'Poser' cover pops up, they can immediately identify it as such.

'Poser' art, when poorly done, is readily identifiable as 'Poser' art. I have not seen your art. You may be well past this, but the first thing you might want to concetrate on is making your final renders look less like 'Poser' art. You accomplish this with judicious use of postwork using Photoshop or whatever. Part of finding your 'style' is accomplished through postwork, what you do to make your art individual.

Having said that, it's all down to taste. Make what you like, what pleases you. If you try to please others, you will most likely fail. Find your audience, the people who like the kind of art you produce, and market to them.
