"Please create a surreal, contemporary illustration with a touch of Fantastic Realism. The composition should depict a portrait split in half, where one half features the face of a young woman with soft features and bright eyes, and the other half displays the face of a classic sheep completely black, without the presence of horns. The look must be highly realistic, especially in the details of the character's skin and eyes, but with clearly fantastic proportions and elements, such as large eyes and lush hair decorated with flowers. The illustration technique should be modern, with smooth gradients and meticulous attention to detail, typical of contemporary digital illustration. Additionally, the surrealist element must be incorporated into the work by fusing natural elements, such as flowers and a butterfly, to create a composition that defies conventional reality. The flowers must have organic and curvilinear shapes, in a style reminiscent of Art Nouveau. Please ensure the illustration is high resolution and follows a digital format with a 7:4 aspect ratio. The setting should represent an outdoor environment in an open field during twilight. Thank you for ensuring that the transition between the two halves of the portrait is natural and smooth, eliminating any hard lines or visible discontinuities. The end result should be a work of art that captures the essence of Fantastic Realism with contemporary and surrealist influences, whilst maintaining a sense of beauty and mystery.
