More values and some form stuff, etc

To expand a bit on this.

When drawing, especially when drawing a cast like this you need to realize that the range of value with which you can play around is much smaller than that of which you are trying to depict.

A bright bright in nature is going to be sharply reflected light, a dark dark is going to be a complete absence of light.

This means we need to cheat, we need to trick the human eye with an illusion, and the way we do this is by compressing the values. This way we can strive to at least retain the comparative relationship between areas of light and shadow

Specifically we need to compress primarily the darks.

Since the whole deal with seeing in the first place has to do with reflected light it makes sense that we would want that maximum amount of cowtools to express areas of light.

This is a good example of what I am talking about.

Notice how the shadows are a very limited range of values.

This cast is being much more sharply lit, but the point remains.

And your bright bright s still aren't bright enough.
