This is my first entry into the '1# Drawitbetter Contest' hosted by @sirsensei.

The Theme is: 'Sensei' (which means Teacher)

This is quite an interesting theme, I drew a popular character in pencil and maybe you can recognize him.

See below my entry.
Hope that you like it.

As the theme was "Sensei", I drew a teacher, and it is based on "Professor Severus Snape" from the popular "Harry Potter".

To start off, I began a rough sketch of the Sensei

Then I drew more detail and some shading

Some fine tuning

Adding my user name

And then some editing on computer

Thanks for your time and have a great day!
