You should try downloading some of the free lightsets, Poser's lights are hard to get right (at least to me) and your character looks a little dull/dark to me. You need to work on that grass too, try a new layer so that some of the grass goes in front of her feet and wall and stuff. For a first render this is pretty good and the things to improve are mainly in the post work fase. The thing about the grass not showing... Did you render over a background image? Png's (and tiff's) have an alpha channel in Poser, that's why it didn't show up :o) I like that stone wall :o)

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
