If you can do that in 15 minutes, I'm pretty sure you could achieve much better results (aka the drawing looking more like Mike) if you put more time and calculation into it. I wouldn't be saying this if this had taken you an hour, but like this, I think you can do it.
This looks like you combined the faces of, like, half the members in a face-morphing application and, then, sketched the result in fifteen minutes.
