The light house challenge was somewhat difficult.  I had a troublesome time dealing with the lighthouse itself due to the poor quality of the photo.  I cut out the lighthouse and the tree next to it and used images I found online to place it in a completely different setting.  Then, I used different pieces of sky to create a cube images and a hold where the cube came from.  I added in little details to add immersion like the lighthouse keeper in the bottom left, the birds, and the clouds coming over the sky cube.  The videos did not really help me due to how unusual my idea was for this design.
