Independent Study : end of week 3

So the 7 images below is my independent study for the end of week 3. After working with my 7 design principles in google SketchUp and making them 3D we were then told to develop them into more interesting 3D images - i tried again to use the shadow tool but i was still unsuccessful even after talking to my teacher. I feel as though a lot of my 3D extended images would look better with shadow but i have compensated with changing the style, colour and and turning it translucent. Enjoy :)
