Hey Turbo Dan - good work so far. Well done mate.
I still think the foot needs a bit of work. At the moment the big toe is not really working for me - it's just looking a little flat on top. Also, if you look at your reference picture you can see that the wide points of the big toe are offset at an angle. I don't really see that in your model at the moment. I also think you need to work on the bump on the outside edge behind the big toe - the bunion area.
As for the head, it is definitely going in the right direction, but I think the eyes are way too high, a common problem it seems. Some more screenshots of the face from different angles will also help - it looks like your ears may not be in quite the right place and the inside edge is looking a little straight.
Anyway, your model is definitely coming together. Keep it up.
