One of my favourite artists - Kilmany-Jo Liversage. 
Former high school teacher Kilmany-Jo uses a graffiti style to create striking portraits of women.  
She's not normally a street artist but does have a couple of pieces out there. This piece was painted for IPAF 2020 (www,ipaffest.co.za)
She's also designed murals for a series of Nandos stores worldwide, including in Melbourne. 

From ipaf.co.za:
"Kilmany-Jo creates portraits that sit at the blurry boundary between fine art and graffiti.
Adopting the graffiti or urban art language allows her to update, renew and challenge the conventions of painting, though her rendering of female subjects are inspired by Renaissance-era portraiture. It also references digitised mass production and a futuristic post-human world, populated by perfect-looking female cyborgs,. The result is a series of brightly coloured large-scale paintings, evoking the street, art history and the future."
