Portrait Challenge

I tried this challenge before, but I wasn't that successful, so I thought: why do you not try it again? 

 Note: I won't upload every portrait singly (I already drew 3 ones, but I'm not really satisfied with the second one, so I don't post it yet). But, if I succeed in this challenge (hopefully), I will upload a picture including every portrait I created - a collage of a sort. ;)

Enough with the jaw, let's start :D.

The following portrait was actually the first one (above is the third):

It doesn't precisely look like me, but I am still quite happy about how it turned out. :)

However, the main thing is that I practise a lot and learn something about the light and shadow ratio in the face and how the human head itself is constructed. 

 Furthermore, to draw a portrait with the aid of a plain mirror or in general from real life is pretty much the most difficult thing which you can think about when drawing.

So, reproducing my face is just a minor matter ;).

That's it for now with the challenge ~

Some more doodlings:
