1. The practice of the sun: First, you draw a circle, choose the gradient tool and choose to fill the neck, and you can draw the picture effect yourself.
2. Halo method: Similarly, you draw a circle, turn it into a selection, and choose to shrink inward by 2 pixels. Then fill it with the color as shown in the figure (there are many methods, so I won't introduce them one by one).
3. How to make lighting: Make a selection with the pen tool, then select the gradient tool, select the linear fill color, then change it freely, copy the layer, select an angle, click once to copy the number of layers you need, and perform the last step again. If you can use shortcut keys, so much the better. Just hold down Ctrl+Shift+Ait+t to execute again. As shown in the figure, the light size is different, so you need to adjust the light size and choose the free change tool.
I hope I can help you, it may be a bit messy, I hope to adopt it.
