These are my sketches. I wanted to include the polish flag in my crest, because I am 50% polish (my mom is 100% polish). I also wanted to include music somehow, because everybody in my family plays at least one instrument, and for some of us, music is our passion. I also wanted to represent that a lot of my family is made up of engineers.

This is some of my inspiration. On the right is the Polish flag. I really liked the crest on the left.

This is my final product. The four music notes on top represent how each of my family members plays at least one instrument, and the four notes represent my three brothers and I. The  hammer and wrench represent that a lot of my family is made up of engineers. The whole flag makes up the polish flag.
