You don’t owe anyone “pretty” ever —
BUT if you are doing a Venus soul retrieval, if you are exploring your own Venus nature (INSIDE AND OUT) pondering pretty can be part of it. Doesn’t have to be. But can be part of it and can be fun.
In part you can figure out what your notion of “pretty” is or “pleasing to the eye” is by noting which images you respond to, and then perhaps incorporate something of those images into your Venus expression.
