This assignment was to do three finished pieces using either two or three point perspective and adding some direct lighting elements using a curves mask (you make a curves layer, up the brightness then inverse it with "command I"then using white paint in the patches of light you want. It keeps your structure which is nice.) I think the top and parts of the bottom one worked out alright but the middle needs more work. I need to work on detailing things out a bit more. I think it will become easier as my visual vocabulary for environments increases.
