After making her acting debut with the film Pathinettam Padi (2019), she has since starred in the Karikku Fliq mini series Average Ambili (2021) and Mukundan Unni Associates (2022) as the female lead.
Film critic Arya U.R of The New Indian Express wrote that "Arsha’s acting, where she would speak volumes with a glance or smirk, is one of the most striking elements of Average Ambili".
[5] The following year, Aarsha appeared as the female lead in editor-turned-director Abhinav Sundar Nayak's debut film Mukundan Unni Associates, co-starring Vineeth Sreenivasan, Suraj Venjaramood, Sudhi Koppa and Tanvi Ram.
[6] Vignesh Madhu of Cinema Express commented that "It is rare for mainstream female actors to get roles that shatter stereotypes, and Aarsha lapped up the opportunity with both hands".
[1] Aarsha also starred in costume-designer Stephy Zaviour's debut film Madhura Manohara Moham[7] and Qurbaani co-starring Shane Nigam.
