If you have some of your batch [the one you've shown] left over, try reheating it and adding some of the smaller green glitter to it and then shoot another run of baits just to check and see if things darken up that much.
I don't know if you do this or not, but take a chunk of that original scrap, bag it in a small ziplock, and hang it on your wall with the name on it along with the recipe you've shown written on the bag with a sharpie. That's a nice color as it stands and a guy can never have recipes written down in too many places.
