Great pic for a newbie, you have set it up well.
If you plan on getting a lot of props  (check out the freebies section by the way it is awsome!)  Then put extra  folders in your content folder such as 'people' , animals, structures, vehicles etc. That way you are not hunting all over the place in one HUGE messy folder like mine originally was. If you want to contact me through the site mail I can give you a copy of what my folder set up looks like. Keep creating. Jenny
