The Poser 4 models and the Vickie and Mike figures have many built-in morph targets. Click on the head, and adjust the shape of the face, eyes, nose, mouth, etc. It takes some time, but you can create very distictive looking faces. (Also, there are many additional morphs available at sites like morphworld, etc.) As for more realistic renders, again, it's a matter of taking the time to work with the program. You can use texture maps to make the skin look more realistic; play with the highlight colors and values as well. Try manipulating the lighting -- use spot lights to punch it up. Transparancy maps can make the hair and eyelashes (and eyebrows on Mike) much softer and more natural. Finally, while you can render fine images just using Poser, to really polish the image you should take it into Photoshop or the like and touch it up. Get rid of all the jaggies and artifacts, draw or paint hair and clothing, adjust the levels, try some filters to liven things up. Check the links here and at other sites. There are lots of tutorials out there by people who have mastered different areas of the program. It's like any artistic endevour: you need to put effort in to get results out! Good luck!
