I worked along with the video to make my own study.  It's nice to go back and practice the basics when you're struggling with more complicated final pieces.  I mainly used burnt umber, ultramarine blue and a tiny bit of neutral tint for the grasses on Arches cold press paper.  I've been noticing more and more how I always like my work better if it's on loose sheets instead of blocks, so I'll be doing some more experimenting with these techniques moving forward!
