Aside from the text ‘art party’, it is not clear what your flyer is about. Who is this girl? Why is she important? How is she associated? Would your audience know right away? If so, that makes sense, but for someone not associated, the flyer does not obviously state its purpose. I would also not repeat ‘dj party’ so many times, or are these place holders for names later?
I think the strokes are nice, but there should be some bolder strong colors to make it pop. Your ‘art’ also is the only piece with teal and it washes out the letters as the color progresses, so I would recommend keeping it completely black to maintain legibility. Keep up your creative flow!
