Hjalmarsson's portfolio serves as a visual diary, capturing fleeting moments and

emotions in an attempt to create a sense of permanence in a transient world. This theme

is evident across her portfolio, which she describes as a "love letter to life," where each piece

is a proof of existence and a testament to the significance of the moment it portrays​

​

This idea is perhaps most present in her project "To My Muse," where she turns

the deeply personal into the universal, offering an intimate exploration of love,

partnership, and the creative process. The series feature multiple oil paintings using her partner (musician Andy Yeo) as a muse to commemorate an era of their life while also exploring the traditional dynamics of portraiture.  Through her female gaze, she explores the complex relationship between artist and sitter, infusing the pieces with contemporary pop culture references, art historical nods, and personal anecdotes unique to their partnership. By placing herself in the traditionally male-dominated role of the artist and portraying her male muse with deep respect and adoration, the series challenges the conventional gender roles in art.
