a charming oil painting of an otter standing upright in calm, reflective water, exuding curiosity and playfulness. The otter's fur is rendered with meticulous detail, capturing its wet, textured coat glistening softly. Its expressive face, with a slight tilt of the head, conveys a sense of innocence and joy. The tranquil water reflects the otter's form, rippling gently to add depth and movement to the composition. Sparse branches extend into the scene from the foreground, creating a natural frame that contrasts with the serene white background. Use soft, blended brushstrokes to enhance the reflection and subtle ripples, while emphasizing the otter's endearing personality and the peaceful, minimalist atmosphere.
