Skills needed for digital art

For digital art, you definitely would not need any skills that you need for traditional art.

However, you do need to know how to use the paint or drawing programme to create your art.
One common thing that both of the artists need is the concept behind their art. At the end of the day, the artist must be able to convey the meaning behind the artwork to the audience. so the artist must have a creative and an imaginative brain.
