Creating a great design isn't easy. For this week, take the time to really hone in on your designs and do proper research to ensure your design is functional. The function of the design will inevitably lead to the form itself.
Focus on the functionality and form of the port design
Show us a final design of your port (and ship). If you're still unsure then do a few iterations so we can help you solidify on a design. Most importantly, do good research and look for good reference so you can understand how your design would work realistically.
This time, try to look for specific reference that'll solve any questions you have rather than just because it looks "cool". That's what defines a good reference board.
For example: How is your ship powered? What type of era/world does this port belong in? What's the level of technology utilized? Is it influenced by a certain type of culture? etc. All these questions should be answered through the images you include in your reference board. A reference board doesn't have to compromise of just images. It could include short descriptions or keywords.
