First off, I don't know the capabilities and limitations of Poser, so I apologize in advance if I suggest anything difficult/impossible to do.
I like the pose of the first one, though I think it would help her look more halfling-ish if she were looking up somewhat. I like the hair from 1 in style, but could you darken it to a fairly deep brown. (sorry for not mentioning that in my first post.) The lance looks good, and I like the pointy ears but I think there slightly overdone. The face is also a good match to how I imagine the character.
However, I like the body proportions from the second one. They feel more like those of a halfling rather than a tall and regal elf. I also like the clothing texture; it feels like something that might have been skinned from a dinosaur. I also think the not as tight pants are more plausible looking. Its not a big deal, but if you can get rid of the belt buckle easily it would give more of a druidic feel.
I'm afraid that the revealingness of the clothing on the upper body would likely offend the player its intended for. The armor from 2 over a rough-spun shirt would work, as would heavier hide armor. Adding some sort of tribal pattern into it could be cool, though I could proably do that myself in photoshop once its done.
Sorry about the number of requested changes. If anything requires that you buy a new model, I'd happily cover the price for you (within reason, of course.
Thanks again for doing this.
