Sharing experiences or thoughts on how to improve the process is not arrogance, I appreciate it. And you're right, the paint application should be so minimal as not to damage the details, and the paint droplets should be very small. I will try not to paint the model entirely, but will apply the paint as dust, allowing the plastic to show through this layer of paint. This way, I will introduce minimal distortion to the size of the part and avoid spoiling the details. Another issue is that I don't have such a long-focus lens. I have a 300mm lens, but the minimum focusing distance is large. I also have macro rings and a teleconverter. I also have a 500mm mirror lens, but unfortunately, it's not suitable for this purpose, as its minimum focusing distance is approximately 4 meters. In general, I will experiment.
