So far in this class, I believe these are my most improved or best ones. While in the charcoal stage of the class, I have definitely been able to see i better improvement in value and other details. I love working with charcoal. To me it is easier. I think that is why most of these are my favorite ones. There are a couple that i really wish was finished because they would be so much better, but even how they are right now they have so much detail and character in them.
