The first image was my initial attempt on Chris's "homework". A day later I opened up a photo of the portrait on my tablet and measured where the proportions were off - and tried to correct it. I think the biggest changes were the proportions of her forehead, nose and neck (and values).

 

 

I think it resembles her a bit more, I'm looking forward to work on other courses by Chris, thank you for the opportunity and your hard work!
