/ic/ - Artwork/Critique

I would appreciate some crit/advice on my bargue plates. I got into drawing a few months ago and I feel like i'm improving in terms of accurately copying what lines I see, but I still find blending and placing correct values to be challenging and would appreciate any advice. (I know some lines were rushed, especially the ears) I don't know any easy way to post all the references, but they're drawn in order from bargues drawing course.
