So I had some problems with placing my modeled light bulbs onto a background image but for now here is an image of two light bulbs I modeled. One being on and the other off.
I put my giraffe in an African background with a nice ground shadow. I couldn't figure out how to install Yafray to blender so I wasn't able to get as clean of an image but I can figure that out in class tomorrow.
This is my second attempt at arrays and with the use of texture and a more interesting starting shape I think this one turned out much better than the first.
