This is a sketch-style illustration, predominantly monochrome, portraying an anime girl and a cat on a balcony with an intricate European cityscape as the backdrop. The artwork is highly detailed, with meticulous rendering of textures and patterns.  The girl is standing on the balcony facing away from the viewer, giving us a rear view. She has short, bobbed hair with incised details indicating strands and shading, and the hair partially obscures her face, which is visible in profile. Her hair is adorned with an accessory that looks like a bow. She is wearing a round-collared blouse with ornate patterns on the shoulder, possibly lace or a ruffled design, and a pleated skirt that falls above her knees. Her outfit gives off a slightly vintage or classical vibe.  A spacious knapsack with a quilted design rests on her back, featuring distinct stitching lines and a pattern that resembles leaves or scales. The bag is rendered with shading to provide a three-dimensional look, and two drawstrings hang from it.  The girl's side profile shows a calm expression while she gazes out over the city. The cat, with a collar around its neck, sits serenely on the balcony beside her, facing the viewer, and shares an equally placid demeanor.  The balcony railing is ornate and wrought-iron, demonstrating the artist's attention to detail with its curlicues and floral patterns. Below and beyond the balcony, there is a dense array of buildings, each detailed with windows, balconies, and roofs. The city stretches out into the distance, with the perspective creating an immersive sense of depth. Some buildings are highlighted in the background with a slight sepia tone, providing a subtle contrast to the otherwise monochrome palette.  In the distance, hints of foliage and architectural variety can be observed, and the sky is implied to be broad and open with a few sketchy birds in flight, enhancing the feeling of an expansive city environment.
