You can use contouring tricks to round out your face more. The idea behind contouring is to create what looks like subtle shadows. Anywhere you want to look bigger, use a slightly lighter shade of makeup. I also have an angular face. And subtle contouring can look great on a human. I tend to use lighter shades on the hollows of my cheeks to round them out more. I already have high cheekbones. So I don't hilight them.
