Emotive por­traits, raw, expres­sive styles
Fashion (casu­al chic, boho, glam rock, etc.)
Androgynous, tomboy
Avant-garde fash­ion and fash­ion nudes
Film noir, Hollywood era, Femme fatale
Experimental, weird, quirky, surrealism
Underwater, oth­er­word­ly and ethereal
Fantasy, Asian myths and legends
Hommage to Vietnamese culture
