The chart that Logan posted looks great, especially the lists of adjectives.
There are just a few things I might add.
1. I like that you noted Willy’s plain attire, and I think it is also important to note Willy’s age, despite his often childish irritability and attitude. Miller makes a point of saying that Willy is “dressed tiredly.” Also, Willy is reluctant to get new glasses, so he is wearing old ones. Willy is past sixty years of age and has been worn down over the years.
2. Happy is described as “well-built” and he is also ambitious, but living in delusion, just like his father. Happy is also self-centered, vain, and hedonistic.
Thanks!
