For the dog icon, I focused on my intuitive drawing to realize the necessary details for clear visual communication. The snout was my guide. I added the (whisker) freckles in order to clarify dog, rather than other possible translations, such as bear.
Since the purpose of an icon is to communicate something clearly with a reduced amount of visual information, do I need a windshield to communicate VW bus? The unique, grill shape seems to carry enough information for the specific emphasis.
(in real life, I have very few shoes)
I am still in the process of deciding if the lace holes are to be the focus or the laces, as well as adding a tread to prevent the viewer from interpreting these as... corset.
