I've been working on this sketch of John McCain for about a week now. I'll only spend about 5 or 10 minutes per session on it, so that I can keep coming back to it with fresh eyes. Like I've said before, I struggle with values, especially balancing them throughout the drawing, so I'm hoping these types of sketches will help me improve.
I'm posting it now, as a work-in-progress, with the hopes that some of you will be kind enough to leave any comments, suggestions or critiques that come to mind. Believe me, any and all thoughts are greatly appreciated.
