The designs I have submitted show the aerial view of ships docked in the ports. The 'SPE' letters represent the ports that the ships dock into, and the ships are represented by the rectangular and rounded rectangular shapes which fill the gaps in between the letters.
I have made these designs especially unique to allow the SPE company to gain effective recognition.
If you would like me to make any alterations to any of my designs, please do not hesitate to contact me.
