1) Well what makes it substantiate in society with females it shows, a lot of self confidence and a little over exaggerated.. In stanza 2, lines 4-6, it says they fall to her knees and swarm around her. Well in reality men falling to their knees seem alittle over the top. I think it definitely symbolizes a strong confident woman, but when you substitute perfectionism with females on reality; it states in the first stanza, "I'm not cute or built to suit a fashion model's size" which to me states that she still feels phenomenal even when she knows "she's not cute" or models size" she still feels phenomenal.
2) Angelou uses these repetition phrases like "I'm a woman" "that's me" and in the poem Still I Rise, they express the saying "But still, like dust, I'll rise." or "I rise" in the end of the poem to show a level of confidence where noone or nothing can lower this level of confidence of them. It's saying this is me I'm a phenomenal woman to show how she accepts who she is and is proud of who she is. In Still I Rise It it uses te reputation of "I'll rise" saying no mater what happens or what you do this person will still do what he/se wants. It's a level of confidence that corporates these two peoms together.
3) The main point of this poem is no matter of you think of yourself as "cute" or " model size" are phenomenal no matter what, the poems stating she's a woman, and she's proud of who she is. So that main point is that level of confidence or understanding of you.
4) Some literal techniques used in the poem to describe indiviualtiy were self image, confidence, and a lot of personification to describe her individuality as a woman.
