Pretty cool drawing of Kanada.
The shadows around the face is a nice added touch.
The shadows around the nose and eyes will look a bit different because of the distance.
Skull anatomy and how flesh wraps around the head is a little bit complex.
The drawing style of Akira is not entirely realistic but a very stylized version of realism influenced by the artist's own interpretation of reality.
You are seeing reality through the creator of akira's eyes.
It is possible to take akira fan art to the next level by injecting your own interpretation of reality into an already strong piece,
I do enjoy that you drew Kanada entirely within your style and I hope to see more your works taken to another level of stylized realism.
Keep at it.
Very cool.
