Looking at your reference upside down is the next exercise in "Drawing Right." I admired Juliana Coles' self-portrait the current CPS pictured below. That cowgirl's got skills, y'all. See more in her etsy store.
I followed it loosely and this is my result.
Not a great facsimile, I gave mine curly hair and made a couple other edits - some intentional. On the whole, it doesn't stink. I think my portrait looks a little like Linda Hamilton in T2, you know, when she had the killer biceps?
