She has stated that she aims to "depict the psychological and social effects these [colonial] views have upon people of First Nations, minority groups and the general public. My Aboriginal ancestry allows me to closely and critically analyze Eurocentric views within my everyday life experiences and to more clearly understand other Aboriginal voices of the past and present. The ultimate goal is to disseminate an awareness of these conditioning effects and hopefully bring about a greatly needed change of thought."[6]
Longman's sculpture Ancestors Rising was commissioned by the MacKenzie Art Gallery in Regina, Saskatchewan and marks the Saskatchewan centennial as well as a First Nations presence in Regina's sculptural landscape. On National Aboriginal Day, 21 June 2006, this sculpture was unveiled in front of the MacKenzie Art Gallery in Wascana Park.[6]
Her family experiences have influenced her work. Longman's mother was born in 1949 and was put in residential school as a child. The digital art work titled Warrior Woman: Stop the Silence!! was created in response to her mother's experiences.[7][8]
Longman was a recipient of the Distinguished Alumni award from the Emily Carr Institute of Art and Design (2000), Lieutenant Governor Award finalist in the Saskatchewan Artist Award category (2012) and the Provost Teaching Excellence Award in Aboriginal Education (2015).[5]
