NYE With a Bang | Event Poster

Hey people!! I'm very new to design...this has been my first assignment for the Diploma in Graphic Design course I'm doing and I would just like some feedback...just so you guys can know what I've been working with, I have attached the design brief. :) Would appreciate any feedback I can get! Design Brief Background A city council is planning a New Year’s Eve party for under 18s. The event will be in the capital city of the state or territory of your choice. This party is targeted at people aged 13 to 18. It is a no-alcohol event and there will be no pass outs. Special care should be taken to promote the idea that the event is divided into timeslots to allow people to choose the type of live music they want to hear. The promotional material must showcase the event by the use of images, illustrations and some text. As this is only a visual concept, large amounts of text are not required. The working title of the music event is ‘NYE with a Bang.’ The evening will be divided into three timeslots: hip hop – 6 pm to 8 pm, pop music – 8 pm to 10 pm, and R ‘n B – 10 pm to 12 pm. It will culminate in a fireworks display at midnight. Your task Your task is to develop an A3 poster for this event. This concept design will cover the basics of the event. Your promotional design should not be too content heavy, and it must use images to promote the city and New Year’s Eve. Design Constraints: Colour: CMYK Use of the logo for the council of the capital city you have chosen: logos must be approx. 105 mm wide, and must be placed in the bottom corner of the poster (left or right). The poster must be clear that the event is: Under 18 (13-18), tickets are always required, no pass outs, midnight fireworks show, no alcohol, full security present.
