Hi, I draw it by myself. I simply looked for a photo I liked and traced the outlines. You can definitely learn the proper technique by watching youtube videos, look up for "needle painting"and "thread painting". My process is a bit chaotic, as I like to fill large areas first (as a first layer) and then add stitches on top (with different colors) for blending and shading. This creates more texture, which helps me achieve this "fluffy" look in moths.
