Oh man you're doing a great job! You're such a great artist because it takes great skill to draw that hair with the sunlight on it!
Overall I love this drawing. Just like your previous Motoko drawing, you did an amazing job on the hair. It has so much solidity and depth to it!
And the orange light caused by sunset has been drawn perfectly both on her eyepiece and on her hair. The reflection on the eye piece is really great too, I can tell that it is an extremely shiny chrome covered thing.
I guess the only part which I believe you could have done a better job are her lips. They are too dark on the shadow side of her face and too thick, I believe it makes her seem older.
Overall, it is a great piece. I have recently just re-watched all of the movies and the TV series and I'm in the fan art mood right now. It has been 6 years since you submitted this, and I would love it if you drew some more of these to quench my thirst for fan-art!
