The Brooklyn Rail described her 2021 solo show as "the visual equivalent of a panic attack you don't want to wake up from." Meanwhile, Frieze Magazine noted that her use of digital decay "makes the virtual world feel more physically painful than the real one."

Furthermore, a comprehensive monograph titled The Space Between Heartbeats is scheduled for release in late 2026, which will catalog over 200 pieces of her work alongside essays by neurologists and trauma therapists, underscoring her unique ability to render invisible psychological states visible. The keyword Rena Fialova work encapsulates more than just a collection of images; it represents a philosophical inquiry into the nature of seeing and being seen. In a culture obsessed with high-definition clarity and algorithmic perfection, Fialova’s commitment to the blur, the glitch, and the gap feels almost rebellious.

However, the defining shift came in 2018. Fialova began integrating digital glitch techniques into her traditional oils. She would complete a realistic oil portrait, then photograph it, manipulate the digital file to create "errors" (banding, pixel sorting, chromatic aberration), and then re-paint those digital errors back onto the physical canvas using acrylic glazes.
