Adjusting project in accordance with crit feedback

In accordance with the crit feedback, I have altered my model to adjust lamp settings (changed to sun and reduced the luminance via energy rating value below 1). Also changed the background to black and deleted the fence lines through editing faces. What I discovered is that I actually had two models inserted into my composition and this was causing issues with lighting of my stage in the rendered images. So I selected the top model/ tabbed into edit mode/ W/ remove doubles.

I also noticed a few issues with the ground level being deleted. After no avail with face stitching, I created a base plane to work with for simulations.
