Gum is her natural enemy.

Her hair

O fleece, that down the neck waves to the nape! O curls! O perfume nonchalant and rare! O ecstasy! To fill this alcove shape With memories that in these tresses sleep, I would shake them like penions in the air!

Languorous Asia, burning Africa, And a far world, defunct almost, absent, Within your aromatic forest stay! As other souls on music drift away, Mine, O my love! still floats upon your scent.

I shall go there where, full of sap, both tree And man swoon in the heat of the southern climates; Strong tresses be the swell that carries me! I dream upon your sea of amber Of dazzling sails, of oarsmen, masts, and flames:

A sun-drenched and reverberating port, Where I imbibe colour and sound and scent; Where vessels, gliding through the gold and moiré, Open their vast arms as they leave the shore To clasp the pure and shimmering firmament.

I'll plunge my head, enamored of its pleasure, In this black ocean where the other hides; My subtle spirit then will know a measure Of fertile idleness and fragrant leisure, Lulled by the infinite rhythm of its tides!

Pavilion, of autumn-shadowed tresses spun, You give me back the azure from afar; And where the twisted locks are fringed with down Lurk mingled odors I grow drunk upon Of oil of coconut, of musk, and tar.

A long time! always! my hand in your hair Will sow the stars of sapphire, pearl, ruby, That you be never deaf to my desire, My oasis and my gourd whence I aspire To drink deep of the wine of memory.

• Charles Baudelaire

I don't really even look at the hair since the face is so good. But since you asked, I think adding fine details would help if you want to spend the time. Use a fine, line brush to go over, under and around. Use them for the highlights and the shadows. Great job.

I can't help you here, I really like what you did. Looks great.

Have my rambling thoughts!

Buying a brush pack is helpful in this circumstance unless you’re wanting to figure out how to do it yourself.

If you’re intent to use the same brush for everything then I would practice tracing over coiled hair to get a sense of how to move your brush. It also helps to watch videos of people with this hair type to see how the hair density changes with the lighting- at some angles it can actually look quite sparse compared to what you might expect in your minds eye.

I like to pull the small springs out of broken pens/mechanical pencils and take a bunch of pictures of them stretched out/bent at various angles since it kinda helps my brain focus on the shape by itself rather than being overwhelmed by HAIR.

You also don’t have to detail every single hair coil either- it’s most noticeable around the edges of the hair, framing the face, and wherever the light is brightest. It’s kind of like texturing trees or grass in that way.

Tbh what you have now looks like a good “base” that just needs more detailing. Could use a smaller brush to do a few highlight strokes or wisps of hair sticking out here and there. Some thicker parts could be faded into the skin colour more around the face.
