Start with the bulkhead at your back. The side profile top angle is 4 degrees down and the bottom is 7-8 degrees up. The rear following ribs are usually elliptical and you can adjust the widths a bit to get a slight side curve. The head fairing could be a half cone roughly 10" dia. and 30" long. The gap between the front nose and the rear bulkhead could be filled with a panel or something stretchy such as Lycra. It has more to do with riding style than anything else. If you prefer the open cockpit you might try a small lip around the back end to the nose piece and put a radius on the forward edge of the main bulkhead.
