Professional Book Cover Designer for Psychological Techno-Thriller (Kindle, Paperback & Hardcover)

I'm looking for an experienced book cover designer to professionally polish an existing cover concept for my psychological techno-thriller novel. It follows an unemployed engineering graduate from India whose late-night video unexpectedly launches him into the world of social media fame, influence, corporate power, and psychological manipulation. IMPORTANT: I am not looking for a completely new concept or an AI-generated redesign. The concept and composition are already finalized. I need a designer who can elevate the artwork to a professional, bookstore-quality standard suitable for Amazon KDP. The current cover already includes: 1. The protagonist sitting in his modest bedroom. 2. A cracked smartphone propped against engineering textbooks while recording his first viral video. 3. A premium modern city skyline visible through the window. 4. A subtle contrast between his ordinary life and the glamorous digital world awaiting him. 5. Existing typography and overall composition. I am looking for someone who can professionally improve: 1. Overall realism 2. Lighting and atmosphere 3. Typography and title treatment 4. The smartphone screen and the recorded face 5. Perspective and proportions where necessary 6. Fine details suitable for high-resolution printing 7. Print-ready production.
