Most of the time, when it comes to icon design, the simpler the better, but that doesn't mean your creativity should be hindered. Netherlands-based Illustrator Matthias Wentink has used simple structured line drawing to create a range of icons based on his hometown Amsterdam.
Matthias used Amsterdam's straightline architecture for inspiration to create this small project . Each illustration can be perfectly placed over each landmark, which shows you can do a lot with simple design.
