Create a portrait of a 20-year-old woman with a Herculean build, gazing directly at the viewer, set against a lush, beautiful garden. The painting should use a palette knife technique, with large brushstrokes characteristic of the impressionist style. Draw inspiration from the works of Kehinde Wiley and Anna Dittmann. The artwork should avoid elements such as errors, split screens, unnecessary text, signatures, or watermarks, and steer clear of aspects like anime influences or totem pole compositions. Maintain focus on the portrait's authentic impressionist style and dynamic representation.
