Step 2 - Manual edits
Fixed some artifacting (eyes, trees)

Step 3 - img2img (outpainting)
Used "Poor man's outpainting" SD script to extend the image to the left and fill with background elements. This was to result in a 1:1 aspect ratio image with the subject off-center.

Did this 3 times, with the resulting image being 1280x1280

Step 4 - Manual edits
Downscaled outpainted image from step 3 to 1024x1024
