Margot Robbie Harley Quinn

Hello everybody and other dogs on the internet, this is my 2nd drawing with an actual progress flow, so let's get riiiiiiight into the deuce:

This is the final product of the artwork.

First, the most basic details and some shading in the eyes, I originally wanted to show just the outlines for step one but I got carried away lol.

Shading on the nose to compliment the details

For the hair, i drew lines with a light tone, then progressively drew more with darker tones and shorter strokes. I left it like this for now so i can finalize everything in one go.

Details on the right side of her hair

Applied some shadows

Then i drew and shaded the collar

Finally, i darkened all the necessary parts with a 7B pencil, then used a brush to blend the shades

That's it for today, any tips to help me improve my drawings are always welcome,
Thanks for viewing!
