With my new art knowledge, I would probably start new projects at home because I know how to get started. If I see something online that I would like to draw/paint as well, I would be most likely know the techniques to making that if it's something simple like a landscape.
Some new/still going goals I would have would be to still be more creative, and get better at drawing in 3-dimentional form. I say the 3D goal because after seeing how I did on my self-portrait, I noticed how I needed to work on my shading and highlighting that contributes to a 3D- looking figure.
A class that would help me reach these goals in my opinion would be just taking another semester of drawing and painting, but I probably won't do that as I want to do other classes like ceramics. Outside of school, I might watch tutorials on how to make specific artwork and learn new techniques from there that might spark my creativity, encouraging me to make my own art with those new skills.
