It's much better then the before result, no doubt about it, but you can see there is some bleed through around the tiles which causes a blurry look. I opened the screenshot in gimp and zoomed in on the corners of the tiles to make it easier to see. Of course it probably would be less obvious using the real tiles rather then the high contrast ones.
