Everything around him: people, things (still lifes), environment...
All kinds.
He was his own style all of his life.
Pablo Picasso used random people in his art, but he also painted his family
Life around him, his room, people, exteriors...
All kinds of shapes - usual and unusual.
I think every artist uses compisition (if you're talking about the way things are placed and how it looks)
Pablo Picasso created "Dove of Peace" using oil paint on canvas. The artwork features a simple yet powerful depiction of a dove, symbolizing peace, rendered in a minimalist style. Picasso's use of bold colors and fluid lines emphasizes the message of the piece, which became an iconic representation of peace following its creation in 1949.
The real plural of 'medium' is 'media'. In addition to oil painting he used all kinds of media you can think of.
Pablo Picasso expressed his emotions through his innovative use of color, form, and style, often reflecting his personal experiences and feelings in his artwork. His Blue Period, marked by somber tones and melancholic subjects, conveyed deep sorrow and isolation, while his Rose Period introduced warmer hues and themes of love and joy. Additionally, his later works, such as those in the Cubist style, showcased a complex interplay of perspectives and emotions, illustrating his evolving psyche and artistic vision. Overall, Picasso's art served as a powerful medium for exploring and communicating his inner emotional landscape.
Science subjects. Mathematics subjects also help, because science makes use of mathematics. Particular kinds of science are physics, chemistry, biology etc. What are often called the "social sciences" include sociology, psychology, etc. There's also medicine. To be a scientist you don't need to do all of these, obviously. There are many other kinds of science.
Any medium you can think of: drawing, painting, engraving, lithography, sculpture, pottery, ...
I appreciate Pablo Picasso's "Blue Guitar" for its emotional depth and striking use of color, which evoke feelings of melancholy and introspection. The painting's unique blend of form and abstraction challenges traditional representations of music and emotion. Additionally, Picasso's innovative approach to perspective invites viewers to engage with the artwork on multiple levels, making it a profound exploration of both art and human experience.
