Wróblewska is a graphic designer, product designer and digital illustrator who graduated from the School of Fine Arts in Supraśl, Poland. She continued her visual arts education in Germany and Finland, later founding her own design studio. --ArtInHouse.pl with edits by Johnny

Her personal work is primarily in portraits, particularly depicting female characters surrounded by magical auras, who dominate, entice and evoke nostalgia. Her works are meant to tell short stories suspended through time and space.
