Small question: why is Fluttershy's hat look fuzzy and pixelated in the preview, but when zoomed in, the hat is really sharp? Nothing else in the picture looks like that...
Ok How to explain It. First thing - that fuzzy-part contains 616 nodes (additionally that fuzzy-part contains light blur - for soft-effect) - so in preview image is smaller so ratio nodes/area is bigger - what it doesnt mean ? when Image (resolution) is small -some parts of image - are interpolated as You know - something like "cloud or fog" because when resolution is too small image loses sharpness, contrast etc. - And when You are looking at zoomed image (with bigger resolution), it has better sharpness and parts which on preview look just like fog/cloud/or pixelated - on bigger image (I mean bigger resolution) are looking sharped. You should to download SVG file and then You try to look at this image when zoom-ratio= 50%, 100%, 500%, 1000% -then You will see what I mean
