I dont think I need to restate anything that was said above... One thing I will say is since you have a willing and beautiful model to work with, Play around with lighting (indoors, outdoors, availible and natural) and posses. look at other poses on the net that work well and recreate some of them. Watch things like missing bodyparts and skin wrinkles and keep an eye on distracting backgrounds and props. AND ABOVE ALL......have fun with it!
Keep up the good work! & Keep up making the good work better!
