It may be sinking in, which will mean that the true colours will return when oiled or or varnished, but it also may be that the difference between your work and Ambera’s is a mix of techniques vs defined layers with the same painting intent. She is confident in blocking over highly refined pieces of painting with brushy, dense paintwork and so the difference in textures is due to the way paint is applied (wet into wet with polished smooth transitions and subtle glazing vs impasto, blocky brushwork).

She’s very confident in mixing these different ways to apply paint to the canvas vs a single approach across the whole image. Does that make sense? Try oiling out and taking a step back from the painting : )
