the biggest limitation of the tech is that it only does full tones, a pixel can really only be one of seven colors, no shading. Works out well if you only work in those colors though, and the occasional image won't look bad if you adjust brightness/contrasts/saturaion and dither it well
like, this is the progress pride flag and a random image search for "pop art" at 40% extra saturation, you can tell which parts work well but from a bit of a distance even the light blue and pink look good
