Here I've included my under drawings. They set up the rest of the effort. It's much less frustrating when you lay out your major objects. You could practice doing ovals and marking them for eyes, nose and mouths a couple of hundred times.
I'm not saying, don't complete anything in between, but you won't be satisfied with what you come out with until you figure out where everything fits. Feel free to erase it, but as Joe Phillips taught Lue, use the drawing end of the pencil as much as you can!
My drawings started out like Cubist or Egyptian drawings: they lacked depth. Occasionally I was making up the anatomy as I went along, because back then it was more trouble getting photographs; we had to pay to develop anything we took, so between that and the film, it wasn't economical, like it can be today if you are fortunate enough to have a camera in your phone (and fortunate enough to have a phone! Many misunderstandings could've been cleared up with a simple text in those days).
When Lue began drawing, he tried imitating other people's drawings first. Now, we know that isn't the best way to progress. You can measure and copy angles, but they are very difficult to put together. He didn't have much confidence because he didn't practice much, and this makes all the difference.
Look at this. Can you see yourself able to draw this? It's not so intimidating, in its simplest form. With time, you can fully realize your drawings, but start with the achievable and discover the possible---in the very place you thought impossible before.---Lyron
You will like what you get more and more if you appreciate every step forward you make. You may not find yourself back at that level when you start the next day, but if you keep drawing you will find yourself advancing again, looking for new challenges.
The under drawing is the part most people leave out.
