First, thank you for creating such a great program. Let’s make it even better!
I found that the program does not recognise spectacles very well. As seen in the screenshot, the right half of the pair of glasses is pretty regular shaped, wheras the left side is not. I would say, if it (the AI) can recognise the right half, it should be able to extrapolate that and mirror it, right?
This particular image was made using the autopilot, and I found that tweaking the settings did not make a difference in the shape.
