Most testing done with moonbeam model and DDIM
normally test images with,
moonbeam, single image, 20 sampling steps, DDIM, low priority.
With these settings you can make images at no credit cost. You wait a little longer, but you can find the pieces you really like and spend your credits on those to make them better.
There's some distortion in the face and hands on the first generation, but using the image as a reference and running it again tends to fix it enough to start enhancing.
