I was able to implement the drawing sketch through the use of the previous concepts (controlling the alpha of an object, as well as manipulating classes) in the previous class(es). I had a fun time doing the drawing sketch and if anyone is wondering why I choose to do circles with gaps on them was because they were required for the project. I might do my own small project and create a drawing sketch of myself. Asides from that the sound class board is pretty decent challenge. It's not easy and not that hard. I just used the concepts that I know to implement the constructors well. It's pretty fun to program if you're like what you're doing and I am indeed having fun making these sketches.
