The final painting is good. But I suggest you either use a blender after completion of your drawing to get a smooth finish or change the media. If you prefer using pencil colours then use water soluble pencil colours or oil based pencil colours for a smooth finish and great overlapping. Or you can switch to water colour, pastel colour, and any other media.
Despite the roughness, its good.
