Never used a help forum before, but with a looming deadline, I am very open to all the help I can get!
I am relatively inexperienced with Illustrator (most of my knowledge comes from searching up information on Youtube, and from trying to carry over knowledge of InDesign).
I am trying to apply a drop shadow to my shapes in the first image (I created them using pen tool and shape builder tool, just as I did for the second image's 'waves'), but am having trouble with the layering. In the second photo, I've achieved a consistent shadow, but when I try to apply the same effect to the first image (the foot shape that radiates outward), it appears as though one of the layers is under the middle layer. I cannot figure out how to undo this, whether I need to redo everything (which I already have, and it didn't change anything) or make the drop shadow apply to only one side... any help would be much appreciated!
