Yes that's what it is, created my own TI to get the same face throughout. That's the Sharloth37v2 you see in the prompts. The skin though is generated via the SD, however I tend to always use the same 'style' so that may be it: 'RAW photo, a photo of Sharloth37v2, (high detailed skin_1.2), 8k uhd, dslr, soft lighting, high quality, film grain, Fujifilm XT' I may vary the 'lighting' bit but the rest for the past few weeks has always been a constant.
Depending on the model used, the face may or may not come out nicely (for me that is) and I usually stick the created image in 'inpaint' and create multiple versions with different expressions, blurring the face only (as per Mr Fox advice a few weeks ago, I tend to generate quite a few iterations of an image and just keep the 'best' which I then work on). Never had to use photoshop so far (but then it's only 3-4 months since starting to use SD or any of what we have been discussing here).
