Just put a paper over that picture and draw what u see through the paper
The varying color tones in Paul Klee's "Ancient Sound" were intended to be associated with music.
Paul Klee is an abstract artist whose works are influenced by cubism, surrealism and expressionism. Aside from being an artist, he is also a musician, a violinist. In fact, before painting, he would play violin as his warm-up. This is why the color tones in his artwork express the connection to music.
I would (for the first) work on realism in you art. know your features and be able to know how to reproduce them. It would be best to work on realistic portraits of other people, perhaps stock photos off the internet. For fantasy landscapes, I think that things that are trippy are good for fantasy landscapes. weird color schemes and similar things of that nature. hope i could help!
