Modder DassiD says they made several passes with the tool and upscaled the textures by four times Morrowind's original resolution. They've included some comparison screenshots on Nexus, where you can also download the mod. It looks impressive, though it's worth noting that a few other mods have been used in the screenshots to make them look even lovelier.
