Re: drawing a likeness
Jeepers . . . a 45-item checklist.
You'll be better and be faster if you find a way to measure and put down with some certainty the distances between hairline and eyebrows to bottom of nose to bottom of chin. There are several good ways to do that and most good books on portrait drawing cover this. The old brush handle or knitting needle are probably the best. (I quit using a knitting needle because the guys down at the pool hall kept asking to see the socks I knitted,)
One of the things I did that helped a lot was go to our local library and did free 5-10 minute sketches of kids who daily showed up there. I live in a small town and the library is just a couple of blocks away from middle school. The kids would go there to use the library's computers after school.
Out of necessity I started my sketches using the "mass-tone" method. I bought some of those graphite sticks and broke off half- to three-quarter inch pieces, and used the broad side to lay in the overall shape of the face/head. A little more pressure for the eye sockets, beneath the nose, and so on. Then, it was a simple matter to check my distances/proportions and strike in a few marks to show major points and places. Over time I got pretty good at it, and it improved my ability to judge these critical distances.
I had one little kid who showed up day after day for his free sketch. I didn't mind, but I was curious. Finally, in a kidding tone, I asked him if he was selling his sketches on the street for candy money. No, he retorted, I'm giving them to my girlfriends.
