Hey Pete, sorry I haven't stopped by for a while.
Uhm the faces aren't looking too bad, it's a nice improvement. But uhm, the do look squished, almost like you're trying to force the features into the face, one thing that I've found that helps for this is to work on all the parts consecutively, it's a little tricky at first but I do think it helps to fit everything together more naturally. I would also recommend doing studies of just different facial features, it really helps to have a solid knowledge of how to draw the features separately when you go to put them all together.
Keep it up man.
