I took a bit of practice and think I improved a lot. of course it is still not perfekt and there is a lot to improve. But I think I have a proper understanding of the face now.
I could have rendered the face more but I think just for learning this is not that important. I think its more efficient to do more faces than a few in good rendered quallity.
I think from now one it is just a matter of practice to get better. so I will frequently do some faces but move forward to the next assingments.
