Summer Wellness Self-Care Portrait Prompt

9:16 vertical, realistic indoor body care and wellness portrait. 
Draw only one fictional adult East Asian woman who is not a real person.
Appearance is {argument name="subject age" default="late 20s"}.
Place the woman's face center at approximately 50% of the screen width, and the visual center of the upper body including hair, shoulders, chest, and raised arm within the central band of 40-60% width.
Naturally fit from the top of the head to below the chest in the vertical screen, not unnaturally cutting off the head, chin, neck, shoulders, main costume, or raised arm.
Leave the inside of the raised arm and armpit at the left edge of the screen, and the silhouette of the black hair and shoulder on the right.

The woman is raising one arm above her head by a bright window, quietly checking the condition of her armpit.
The face is a two-thirds frontal view turned slightly down and to the left.
Lower her gaze to her armpit, looking down without closing her eyes.
Include a small smile of relief at the corners of the mouth, showing it naturally as a self-check after exercise or on a hot day, rather than shame or disgust.
Do not tuck the chin too much; relax the neck and shoulders.

Facial features are a natural oval shape.
Align the positions of the left and right eyes, eyebrows, nose, and lips.
The pupils are dark brown, and the eyelashes of the downcast eyes are delicately drawn.
Eyebrows are a natural dark brown.
Makeup is thin, with pale pink-beige lips, natural cheek color, and subtle brown eye makeup.
The skin is bright and healthy, leaving natural pores, slight fine hair, and a fine gloss of sweat on the forehead, cheeks, nose, neck, and arms.
Represent sweat as clean water droplets and thin moisture, not looking like excessive oil film or dirt.

Hair color is dark brown to near black.
Tie it in a low ponytail or updo at the back of the head, leaving thin bangs slightly clumped with sweat at the forehead and temples.
Show a few short stray hairs in front of the ears and at the nape of the neck.
Naturally draw the hairline, individual hair flow, and thin clumping caused by humidity.

The outfit is a {argument name="outfit" default="plain sage green tank top"}.
Soft absorbent cotton blend material, with a round neckline, thick shoulder straps, and a daily silhouette that is not too loose.
Naturally include a gradient of deep moisture near the chest and armpits indicating aftermath of exercise or heat.
Do not make the boundary between wet and dry parts hard; realistically draw the fabric fibers, fine wrinkles, and differences in weight.
Do not include logos, patterns, text, or transparency.

The foreground is the inside of the raised arm, face, and sage green top.
The middle ground is the woman's shoulder and chest.
{argument name="background" default="Place a bright window frame and white blurred outdoor light in the background left, and make the background right a pale gray to beige indoor wall and curtain."}
Suppress the amount of information in the background, leaving a clean and quiet indoor atmosphere.

The camera is at height from the woman's chest to face.
A near-distance shot wrapped slightly to the left from the front.
Focal length feel is around 70mm, not distorting the face or arms with a wide angle.
Focus on the face, eyelashes, lips, armpit skin, and moisture of the top, with the window and background softly blurred.
Shallow to medium depth of field.

The main light source is soft natural light entering from the large window on the left.
The light brightens the raised arm, left cheek, bridge of the nose, lips, neck, collarbone, and fabric of the top, leaving subtle shadows on the right side of the hair and cheek.
Color temperature is neutral to slightly warm.
Exposure is bright, but does not lose the highlights of the skin and the gradations of the wet cloth.
Overall color tone is sage green, natural skin color, black hair, pale gray, and white.

Realistically depict skin pores, small water droplets of sweat, natural moisture of the lips, eyelashes, fine hair, and the fiber and moisture of cotton cloth.
Clean commercial photo quality suitable for summer deodorant, sweat measures, post-sport care, wellness, and beauty articles.
Do not include text, logos, brand names, signatures, or watermarks.
Avoid extra people, extra arms or fingers, missing hands, fused fingers, broken shoulders, twisted necks, distorted faces, asymmetrical pupils, over-emphasized armpits, sweat looking like dirt, doll-like skin, over-beautified skin, too strong HDR, or illustration style.
