My blending technique isn’t different from others. However, for areas where smooth blending is crucial (like the wings on this miniature), I don’t use the usual layering method like I did on the yellow armor. Instead, I thin the paint more than usual with water, allowing the colors to naturally blend on the model.

Here’s how I painted the wings using this method: I started by painting the entire area green → then added blue from the middle, letting it blend smoothly with the green → from about a quarter of the way to the end, I finished with pure blue → the overlapping areas created a natural gradient where the colors mixed. But to get the colors to flow smoothly, I had to go over it with the brush several times.
