Here are my tree drawings. Just googled 'how to draw a tree' and tried some of the techniques while the dude was talking.
Drawing with a pencil and ink got frustrating so I used acrylics to try to the clumpy thing that the dude advocates with the leaves - highlighting the top of each clump. Not so sure it was too successful but the paint is better than before with the ink and pencil.


Ugh the lighting is really bad - sorry about that.
