Paint mediums, Acrylic, watercolor, and oil paint.?

you have to add layers to any painting it doesn't matter what medium u use that is how u add texture and details.oils take forever to dry.they add more shades of color and shadows and angles.u can water acrylic down so its not as heavy and i would recommend that if u are a beginner in painting to use acrylic it easier to work with and to clean up.
