Reflection:

One thing that I did well on in this project was leading. I think that both me and Caetano did well in leadership because we made sure we did not stay off task for too long and made sure we got our project done. Another thing that I did well on was listening to Caetano's ideas and making sure that both of our ideas were in our project. One thing that I can improve on in the next project is thinking more critically. If I thought more critically during this project then we could have had more components to our light show instead of what we had. One more thing that I could have done better in my project was being more empathetic. Next project I will focus on being more empathetic and thinking critically.
