Technical male student, 20yo, messy brown hair, black-framed glasses, casual wear, holding a laptop, sitting at a wooden desk, surrounded by papers and textbooks, in a modern university library, with rows of shelves filled with books, warm lighting, shallow depth of field, focused on the screen, with a subtle facial expression, slight smile, wearing a white shirt with a few buttons undone, dark blue jeans, sneakers, relaxed posture, slight lean forward, studying Digital Design and Computer Architecture 2nd Edition solutions, with odd-numbered pages open.
