This poster is balanced symmetrically, with both sides having equal emphasis. Which makes it easier for the audience to comprehend and get the main idea of this poster.

The font used for the wording "Retro Ice Cream", and the colours used for the ice cream reflects the overall theme of retro. The colours are slightly dull and muted, matching the dull grey background. The colour of the "raspberry cherry" is not a vibrant shade of red, but a slightly toned down version to match the overall theme, hence the poster appears more visually appealing.

The alignment and constant rhythm of the flavours of each ice cream being placed consistently and equally above each ice cream makes for a more neater and cleaner poster, again allowing the audience to easily maneuver across the poster for each flavour.  The colours of the ice cream match the colouring of the flavour, again, providing a balance to the poster.

Overall, I like the simplistic design of the poster, where there is equal dominance in both the image and the main text. Although there is no main dominance, it does not matter as the ice cream is able to speak for itself in this design.
