from this quick drawing I can see that you understand a shape. It's so important for an artist. Most of "arters" just copy what they see. You analyze the shape by every line. And it's seen even in a quick drawing.
I've been keeping this in my devwatch for a while because I REALLY like this sketch. It's amazing! I wish I could do a better job of expression why I like it so much, but I'll try my best.
I love the shapes of the features on the face -- the lips, the nose, and the eyes. The lips really stand out to me -- I like the soft but well-sculpted look they have -- there's such a lifelike sense of volume to them and they feel so believable and look amazing. I like how they puff out from the face just enough to seem lifelike, but how they fit really well on the face.
I like the nose a lot. I like how you used the lighting and the shadow to give is depth and dimension, but how it's still simple and subtle, implying a lot of the shape of the nose and the bridge of the nose without cluttering up the face with lots and lots of extra marks.
The eyes are really interesting. There's an intensity in the gaze, but the way they're cast in shadows makes hides them away a tiny bit in a way that adds some mystery and drama. Which is really captivating!
This is brilliant (as in shining?): the freshness of direct expression; movements that add what they should, stopping at just the right moment. There is a balance of composition and tone that appears unstudied, natural, yet is probably the result of many hours getting it wrong bearing fruit in this one moment.
Thank you for this experiment. It worked, in my opinion.
I honestly feel like I could reach out and feel how soft her lips are were I to run my finger across the screen. Your shading really inspires me to work harder on my own. Thank you so much for sharing this!
