Not everybody looks best wearing it contoured like that, some people look better with a "V" some people look better with a crease color so don't think if it looks weird to you that there's something wrong with how you are doing it.
That being said how I usually do it on clients is an all-over highlighter color, then a crease color then the lid color. Different MA's are going to have different ways of doing it that suits them best. This is what works for me. Then I take a soft fluffy eye shader brush and blend the lid color upward into the crease to get rid of any lines. You want it to all blend together, even though it's three different colors you don't want to "see" that line between them. Most people I have taught classes to do not blend near enough. Even if you think you have blend again. That may be why it looks odd to you. Think of the colors in a sunset, you might have purple and red and orange but they look soft not streaky, that's the look you are going for. It's also much easier to do with some good quality brushes. HTH!!
