I liked your attention to perfection concerning the shadows and the "contact" on the floor! Two tips for you: a) you could delete her shoes and then load them again so they don't look "wrong" on the "stilletos" and readjust her feet on ground before rendering and b) if were you, i would render the actors and their clothing in one render(png format to retain image's transparency), with no background just "ground on"...to preserve the shadows and have a more natural smoother lighting since no walls would hide my "pov" then a second render for the classroom and then blend them both renders on photoshop or gimp...to have more details and less "yellowing" on the actors skin texture
Well the penis was a blender file imported. But as to the second part maybe you quoted to the wrong person lolAwesome thanks, what assets did you used for the penis and vagina !?
