I'm trying to recreate this 2D cicular image design with the same lighting where the gold gets a whitish hue at the upper right fourth of the circle to make the whole image look like real gold with the nice dark red background.
I was able to recreate the design but I can't get the lighting right when camera view from top view. How do I achieve this same look where the gold has a nice whitish falloff into the upper right quarter? I want to make it look like a nice gold with the nice dark red color around as in the image or even better.
