Edward seems to have a slightly different set of colours on his coat in every frame. This piece has 80 colours rather than the listed 66, and many of them are unneeded.
I also recommend not pre-zooming your work. Zoomed in like this, it doesn't even fit fully! Upload at 1x, and people can use the site's zoom buttons to see it bigger.
Ok. Thanks for the advice. Still learning the rules of PJ.
