Modeling form long drawing Bastian

Hi Matthew!

My name is Bastian and its been around a year since my drawing journey began. This is my first upload here and im looking forward to your critique. 

I spent around 5 to 6 hours on this drawing which is split into 2 days and I really wanted to keep going but my focus drifted – hence the hair is not rendered at all. 

I used a 2B pencil and 160gsm paper.

I noticed the shape of the face is incorrect but I still wanted to push it and hand in a drawing for critique. This is also my first ever long drawing, which im also proud of achieving and not giving up due to it looking off.

Please ignore the rendered sphere. Im looking for critique on the longer drawing. 

Thank you in advance for your critique and also massive thank you for providing this amazing learning platform.
