The title basically says it all. I want to try out some individual classes at TAD, but I don't know which ones would be most beneficial for me. I mean yes, all of them would probably make a huge difference in my art. Yet I want to take the ones that will help my weak points.

One thing I do know is that I'm terrible at coloring and light value. I'm moderate when it comes to the human anatomy, and vehicles. I'm also terrible when it comes to composition.

I know that I should probably take the Composition and Color Theory class so I'll do that. I want to take a second class as well. Any suggestions for someone of my art level?

Also, here's some samples of my work from my sketchpad to help assess what I need:

I would be extremely grateful for any critical suggestions at all.
