1. You probably won't hit 100% parity just by prompt engineering especially if you want to do your points 3-4. You would need to train a style LoRa. 2. You can use one of the many ip-adapter models but the best result would probably be a combination of ip-adapter + subject LoRa. 3. That would be a controlnet model probably sketch best results would be achieved (for poses) using open or dw pose models. 4. You would do that with inpainting or stable drag. https://stable-diffusion-art.com https://stable-diffusion-art.com is a good starting point.
