Vo svojej tvorbe sa venuje najmä maľbe a kresbe, s občasnými presahmi do site specific inštalácií. V posledných rokoch svoj výskum sústredí na rozprávanie príbehov. Príbehov miest, ľudí, rastlín a zvierat, ktoré stretáva pri svojich cestách a na viacerých rezidenčných pobytoch. Z výletov do krajiny si prináša kresby a skice, ktoré neskôr v ateliéri skladá do obrazov a kresieb, mentálnych máp daného miesta. Mieša svoju osobnú skúsenosť s počutými príbehmi, ako aj s ekológiou a sociálnou situáciou daného miesta. Podľa Mrvovej, maľba má schopnosť zaznamenať príbehy miest, ktoré postupne zanikajú alebo strácajú svoj prírodný a kultúrny charakter. Snaží sa zachovať ich v ich autenticite.
Mrvová has always concentrated mainly on painting. Currently, she works predominantly with the media of painting and drawing, mostly in large format, with occasional crossovers to site-specific work and installations. In last years Mrvová focused her artistic research on storytelling and discovering – new places and people and trying to immerse in the new place and later retell its story in the studio. She takes walks in the countryside or a city landscape and capture these moments in a drawing; she speaks with people or tries to communicate with them directly through drawing. She mix stories that she hears with her personal experience and create new “maps” of the place on this basis. These stories often originate in her personal journeys. In her view, painting has a capacity to fix stories in a way that allows them to be preserved in their authenticity. Simple stories symbolize the constantly changing or disappearing world and places that may no longer be the same in a few years.
