Initiate a new document with the specified dimensions of 2,048×3,072 pixels. To unveil the default white background, double-click on it within the Layers Panel and rename it to “Bg”. 
Proceed to craft the fundamental shape of the guitar’s headstock. Employ the Pen Tool (P) and configure it as illustrated in the Options Bar. Subsequently, draw the shape depicted below. 
Subsequently, establish a new layer, select the Rectangular Marquee Tool (M), and sketch a rectangle of 417×287 pixels. Alter your Foreground color to #966a39 and Background color to #cdac85. 
Navigate to Filter > Render > Clouds to automatically populate the layer with the filter. 
Utilize another filter: Go to Filter > Render > Fibers. 
Apply the following settings for the Fibers filter:
Variance: 6
Strength: 4
This outcome will serve as a surface texture for later use: 
Rotate the texture slightly by initially pressing Ctrl/Cmd + T to activate Free Transform, or by accessing Edit > Free Transform for the same result. 
Rotate the texture as shown below: 
Now equipped with the texture layer and headstock shape, merge both layers. Create a selection around the headstock shape by Ctrl-clicking/Cmd-clicking on the layer’s thumbnail in the Layers Panel. 
Ensure the texture layer is active by clicking on it. Then, proceed to Layer > Layer Mask > Reveal Selection. 
The layer mask will conceal all areas of the texture layer outside the selection, yielding the following result: 
Convert the texture layer for Smart Filters by selecting Filter > Convert for Smart Filters. This ensures that our filters are non-destructive, preserving our original layer data. 
Additional texturing is required to achieve a photorealistic appearance, so go to Filter > Add Noise and utilize the settings shown below. 
Subsequently, bestow the headstock with an Inner Shadow and Gradient Overlay layer style to enhance realism. 
You will achieve this outcome: 
Continue by placing a selection around the headstock and moving it as shown below. 
Invert the selection by selecting Select > Inverse (Shift + Ctrl/Cmd + I). 
Create a new layer beneath the headstock layer (rename the layer to “Shadow”). Next, select your Brush Tool (B) and configure it as shown below. 
Utilize the Brush Tool to paint on the new layer. 
Move the selection slightly as shown below. Add a layer mask by going to Layer > Layer Mask > Hide Selection. 
Convert the layer for Smart Filters. 
Go to Filter > Noise > Add Noise. 
Use the following settings for the Add Noise filter:
Amount: 1%
Distribution: Gaussian
Monochromatic: Checked
Create a new layer. Establish the selection shown below, apply the Blur filter, then decrease the layer’s Opacity to 25%. 
Repeat the aforementioned process to add depth to the lower-right and lower-left portions of the headstock.
