Some of the characteristics/criteria for using the hippie aesthetic are qualities such as:
Altruism
Honesty
Nonviolence
Happiness
Joy, etc.
<h3>What is Hippie Aesthetic?</h3>
This refers to the artistic approach that is used to create art that focuses on messages that talk about important issues in a flamboyant manner
Hence, we can see that when creating art and the artist wants to incorporate elements of the hippie aesthetic, he would have to include the above-listed criteria and he can use the "Roundabout" style to exemplify them.
This is all very subjective and as life goes on we usually come to our own conclusions separate from our parents. I'm personally an agnostic who believes that the meaning of life is to make others and yourself happy.
