I can certainly envision the image you have in mind! For this project , I would recommend a high resolution digital painting to achieve the cinematic , warm color palette you are looking for. It would also be important to incorporate the steampunk elements of the city , as well as the wind blowing in the model's hair to give the portrait an extra dynamic element. I would also suggest giving the model a perfect symmetrical face , as you have requested. This would be the perfect way to bring the portrait to life and give it a more realistic feel. ,
