ok, that was a joke, please don't strike me down, oh mighty pixel God.
I've always been a fan of your great dithering and AA skills. To this day you remain one of the few artists whose dithering I actually like to look at from a 2-3x zoom. I'm not entirely sure how, but somehow your colour choices, contrast levels, AA, line design, dithering and a bunch of other stuff come together in this way that makes your pieces smooth and texturious(a word?), while avoiding the typical grit and yuckiness one notices in most dithered pieces.
The others have all raised some good points on what could be improved so I won't bother repeating anything. I'm just going to continue staring and studying this.
