Create a portrait of a female CEO of a mid-sized technology company, 45 years old, exuding confidence and professionalism. She should have medium-length blonde hair styled in a sleek manner, wearing a smart business suit. The setting should be a corporate office with a modern, minimalist design, including a large window showing a cityscape. She should be portrayed standing, with her arms crossed, looking directly at the viewer with a determined, yet approachable expression. The color scheme should be cool and subdued, with blue and grey tones. hyperrealistic, dslr 2020 quality --ar 3:2
