Anastasiia Onikiienko is a Ukrainian artist currently based in Valencia, Spain. Her academic journey reflects a dedicated search for technical mastery, beginning with classical illustration in Ukraine followed by a Bachelor of Fine Arts in Painting in Bratislava. In 2025, she earned her Master of Arts in Artistic Production at the Universitat Politècnica de València (UPV), where she concluded her studies with a thesis titled Precious Moments: Painted Portraits from Instant Photographs.

Onikiienko’s primary practice focuses on capturing the ephemeral through traditional oil painting. Working from spontaneous photographs and lived experiences, she translates scenes into light-filled compositions on linen. Her work captures moments that might otherwise fade, distilling them into an enduring visual presence that invites a deeper contemplation of the mundane.

Complementing her work on canvas, she utilizes digital painting as a modern extension of her painterly language. This digital exploration maintains the same archival quality and atmospheric depth found in her oils while exploring new ways to render light and form. This investigation into the "instant" is further articulated through subtle, hand-drawn digital loops that allow a narrative to unfold.

Her work offers an ongoing exploration of perception and memory, preserving the significance of the present moment.
