Create a landscape format digital illustration featuring a young Bangladeshi girl sitting at a modern home desk with a laptop, showcasing an engaging and focused facial expression. The design style should be realistic yet vibrant, utilizing a digital medium with clean lines and bright colors to convey a sense of professionalism and enthusiasm. Use a shallow depth of field with an aperture setting around f/2.8 to create a softly blurred background, keeping the girl and her workspace in sharp focus. Natural light should stream in from a window to her left, casting a warm, inviting glow. The background should subtly hint at a cozy home environment with minimal distractions. The focal point is the girl, with key features like her traditional attire—casual yet professional— and an open laptop displaying a computer training interface. Add a slight HDR effect for enhanced color and detail. The text "Start working from home today with a 100% guarantee" should be placed at the top of the image in a modern sans-serif font, using a contrasting color that stands out but complements the overall color scheme.
