Ancillary Task 2 First Draft

This is the first draft for my poster ancillary task. I like this draft, and my final version will probably be almost exactly the same. 
The only amendent I am planning to make is to remove the white box in the top right. 
This was just the sun shining through the skylight onto the wall, and we were unable to cover it up, so I left it. 
At first, I thought it looked okay in the pictures, but I might edit it out, so there is no blemish, as I feel the symmetry would be better if it wasn't there.
