Begin by picking a reference photo. In this case I chose a photo from dreamstime.com.
Open a new project, 1200 x 1800 pixels at 150 pixels/inch.
On a new layer and using the basic round brush (15 pixels, 100% opacity) outline the basic features with color #3C1B06.
Create six layers, Skin, Eyes, Nose, Lips, Hair, and Etc.
Select Skin layer.
We are going to do some basic blocking in.
There are three sections, highlight (Yellow), middle (Green), and shadow (Red).
Block in the basic sections (100 pixel, 100% opacity).
Shadow: Color #E7A172
Middle: Color #FCC498
Highlight: Color #FFD6B1
Do the same for the shoulders and hands.
Blend with the Smudge tool (100 pixel, 50% strength, soft-edged brush).
On a new temporary layer apply blush on the sides of her cheeks with color #F09461.
Use the Smudge tool again to blend it out. Merge the layer down.
Take this time to fix any issues you have with the Skin layer. I reworked the left hand a little.
Darken the shadows using the Burn tool (65 pixels, 12% exposure, Midtones mode).
Move on to the Eyes layer.
Fill the whites of the eyes with color #E0E0E4.
Brighten the center of the whites using the Dodge tool (100 pixels, 90% strength, Midtones mode).
Add dimension to the whites by darkening the outer corners with the Burn tool (35 pixels, 40% strength, Midtones mode).
Add a little color to the outer corners with color #CA9E93 (20% opacity), blend out with the Smudge tool.
Block in the tear ducts and very outer corner of the eyes with color #A84D43.
Add the waterline with color #FECBA1. Use the same color to highlight the tear duct. Blend out with the Smudge tool.
Draw on the eyeliner with color #4C2D21. Blend out.
Outline the eye fold and block in the outer corner of the eyelid using the same color. Blend.
Highlight the center of the lid and the inner corner of the eyes with color #E0B9AA. Blend.
Finish highlighting around the eyes with color #F4D8C4.
Block in the Iris with color #330B02.
Ring the middle of the iris with color #631A00.
Highlight the iris using the Dodge tool and deepen the shadows using the Burn tool on their previous settings.
Draw the little lines in the iris using the Dodge tool (Midtones mode, 40% strength).
Paint a little color #B17927 on the lightest parts of the iris. Blend using the Smudge tool.
Add the pupil with black (#000000).
Finish the iris by adding the shines using color #FFFFFF (12 pixels, 30% opacity).
Add the eyelashes with color #210B03 (10 pixel, 60% opacity). Taper them so that the base (the part attached to the eyelid) is thicker and they are thinner at the end.
The last step on the Eyes layer is the eyebrows.
Start by blocking in the shape with the same color (35 pixels, 50%opacity).
Use the same color (5 pixel brush this time) to draw in the individual hairs.
On a temporary layer, brush color #B77A5E over the top of the eyebrows. Smudge.
Finish up the nose on layer Nose with color #B5734B by sharpening up the tip of the nose and deepening the shadow on the left side of her nose.
On layer Lips block in the top lip with color #BA685F and the bottom lip with color #D16E63.
Add shadows to the outer corner of the mouth and between the lips with color #813F38. Blend out.
Fill the middle of the bottom lip with color #ED9C93 and the middle of the top lip with color #D16D62.
Highlight each using the Dodge tool in highlights mode.
Move on to the Hair layer. Block in the hair with color #230906.
Begin separating the locks of hair with the Dodge tool on midtones mode.
Finish the hair by drawing individual strands of hair with colors #853D25 and #230906 (5 pixels, 40% opacity) .
On the top layer, Etc, block in the white feathers from her hat on her forehead with white (#FFFFFF).
Add detail to the fringe with white (5 pixels).
On a temporary layer underneath the Etc layer, block in the hat and shirt using the same techniques used steps 5-7.
Shadow Color: #DB1F14

Add a shadow on the neck and arms where the fabric meets her skin using the Burn tool on highlights mode.
On layer Etc block in the feathers with white.
Block in the light shadows on the white part of the hat with colors #F5EBE9 (shadow) and #FBF4F2.
Blend using the Smudgetool.
Use white to create a feather pattern in the white part of the hat.
Block in the left side of the box with color #E2DAD8 and the top of the box with color #F5F5F5. Use the Line tool to create straight edges (20 pixels).
Use the Line tool and color #D7D1CD to create the lines on the left side of the box.
Use the Dodge tool to highlight the box.
On a new layer above Etc, create long stringy "ribbons" of cold with color #AA773B (50% opacity).
Block in the ribbons with color #AE0808 (shadows), #E20404 (middle) , #FE512D (highlights).
Do the same for her fingernails.

Brighten the highlights using the Dodge tool on highlights mode.
And you are done!
