In 2019 curator Philippe Batka selected one of Kostova's works for the 12th year of wrapping the Ringturm building in Vienna, Austria.
In 2004 Kostova's installation Fixing Reality[4] was created by placing a large blue screen[5] in several public settings in the United States.
In 2019 her art work “Cosmonaut 1001″[7] which features a baby astronaut with communist and capitalist patches on its suit and a white dove sitting on his helmet, was selected as part of the public installation[8] project Future Dreaming[9] to cover the Ringturm building[10] in Vienna.
In 2017 her installation “Stuck” which was a large-scale photo-mural, was commissioned for the exhibition “Shifting Layers” at the Sofia City Art Gallery in Bulgaria.
The installation was a reflection on living conditions affected by climate change, and the realization that things can dramatically turn overnight, shifting from play into tragedy.
