Secretary Bird - Pen Drawing

Here is my new pen drawing.
It's a sketch of a wildlife creature known as 'Secretary Bird'.

This carnivorous animal looks like an eagle with curved beak and wild eyes - but not. They prefer to hunt on the ground unlike the eagle that hunts from the sky.
It posseses long legs and are used to walking a lot. They fly when necessary.

The drawing was done with a blue ballpoint pen on a cardboard paper. Here are my steps:

Thank you.
