Hey 
I did the Blending exercise - I made myself a template: (maybe it can be useful for some of you?)
Smudge Tool version:

Hard Brush version:
Soft Brush version:
I don't think I'll ever use the Smudge tool much, it's just not for me.
But surprisingly, I kind of like the visible strokes in the hard brush version.
Also I started practicing loomis heads, from a loomis head 3D model, from photos and a few from imagination, I rotated through the 3 types a few times but since it sums up to 180 heads I thought I'd better put them in a gif ^^'

Upwards angles where the underside of the jaw is visible are my downfall so I practiced them a lot.
Time to get started on the features! But I'll probably do some other assignment first to get some variety
