That looks most excellent Mike! Very simple, but elegant. Nice job.
There is an old clown thoght that you never use either yellow, purple or green on your face, but this seems to work for you. (I think the "rule" only comes into play when you're filming....something about those colors doing weird things on video) I think the only thing I can say about using black might be that it will make you look more polished.
As far as design: The only small suggestion I'd make is two pronged and it regards the vertical accents under your eye. I'd suggest making the accents half as long, and going both above and below the eye.
The reasoning behind this is that your arches go up pretty high. High enough that they probably don't move when your raise your eyebrows. But it looks great and I don't want to lose that. So one texhnique to help add mobility to your expression is by adding those accents above. They will move whenever you do an expression such as surprised.
Here's what I mean.
I should add that this is just a little bit of thought from me. Don't change a thing if you don't want to.
