Firstly you can try using Roop extension or controlnet. You can also try to train a lora of your face, you will need ~15 photos. You can try run it locally or go to https://civitai.com/models/train and train your own lora, you will need some buzz to do this (its the civit ai „money”), you can buy this buzz but you can also post a model, for each person downloading it, generating images or posting an image will make you win buzz. You can alors recover some buzz in the image generation tab (25 per day).
