Start sllooowly grashopper jumping in with both feet will get you soaked. Take it one step at a time. Start with whats in the manual get a good foothold and UNDERSTAND whats in the manual.Most of these things will teach you how to move ,light,and position people also how to change the ones that come with poser. Once you get those basics and they are the basics you will understand better such things as morph targets,textures,composition etc. Then you will be able to understand what it takes to make people cloths etc. It takes more tools other than just Poser in order to actualy MAKE new people and cloths.If you don't know the basics you will get lost and frustrated very quickly and then want to give up. A good saying to remember is "you must first learn to walk before you can learn to run."
