Even someone who does a photocomic uses photo references. After all I have to build and set up stuff and need references for that and how to pose the figures. Action figures can do poses that people can't.
"... one of the finest, grumpiest most cynical people in the known universe."
I use photos a lot for cars (and things like that) if I want a particular model, also poses I just can't ge right and any real location, person, etc. I also find models (toy cars, for example) very helpful.
I don't even know what my comic is called any more.
I use photo references for a variety of things, mainly hands and poses from different perspectives (looking up, bird's eye, stuff like that). I also collect images of armor/clothing/weapons/buildings/etc. for research and inspiration.
"Style" is something that will develop over time on its own by pulling together artistic techniques that appeal to you. Even if you look at another artist for inspiration, there will probably be other things that influence you to make it different. (You should also explore many types of art, not just one artist.) Style is something you can guide but never totally 100% control.
Photo references are a tool to achieve your artistic vision for the image. It would be silly to think that your brain can imagine an accurate pose/perspective every single time. Most great existing artists use references, and even the Old Masters used models. So don't ever feel guilty for using them.
I agree with Gary that as an artist you should use as many references as you need, whether that is photographs, models, other artists work, action figures, etc. I will even get out clay and sculpt up a rough of a character so that I can see the play of shadows on the face.
