I want to create a painting in acrylic using the pencil drawing attached as reference.
Is this a good idea, or is it better to start painting in the drawing to improve my skill?
And how would I start painting it in with acrylic paint?
As Flora stated, if you try to put acrylic on top of the graphite drawing, the graphite is going to smear into the paint, and it is to have streaks of graphite into the paint. Causing it to not have a solid color. Also as well, depending on what paper it is, it can become wrinkled or start seeping through the back of the paper. Unless you have paper specifically for acrylic paint. Canvas, wood boards, or acrylic paper would be a good start.
Starting in acrylic, want to start with lighter colors as the base, and add more layers continually on top of the under layers. Also recommended to have a base coat as the first layer. So it gives the acrylic something to stick to. The fun thing about acrylic paint is that it is super easy to cover up with other colors. Can even cover up darker colors with lighter colors. It dries super fast, so it doesn't take much time to add lots of layers.
I would personally paint it separately from the original drawing, for a few reasons:
What I would recommend doing is to very lightly draw just the general outlines of the image onto another paper/canvas/board for painting. If you have a kneaded eraser, it would work really well for lifting some of the excess graphite so that it leaves just the slightest trace of the line behind. (If not, use a good eraser to very gently remove some of the graphite, without smudging.) Then begin painting in the medium shades, then shadows, small details, and highlights.
Hope this helps! If you have any questions, please feel free to ask.
The question was changed/edited after my answer below..... "I think there is no "where" point to start on it, each artist as his own way to paint it, there are obviously some academic rules to think on, but try to think of art like a form of freedom and expression, not strictly rules to chain your creativity. Acrilycs dry quickly so you can go over and over to make adjustments and refine your work.You could start thinking of painting dark then lightness, or inverse it, that could help a bit."
