JFCT doesn't have a CVS Shingo. If you're talking about the PotS Shingo with Dampir sprites, that one is an edit by Infinite. There's also 2Dee4Ever's version.
This is the original SNK sprite from KOF 98.
This is 2Dee4Ever's version with Capcom shading gimmicks on the palette.
This is Dampir's version based on SNK sprites, redrawn to look like Capcom style however, resizing caused distortion on the sprites.
This is Kyo's sprite from CVS2.
And this is my edit. You can see the difference easier this way.
