task 2 evaluation

 

in my opinion I think my poster looks apealing to its target audience becuase i have used large text writings and diagrams to make my poster look more intresting. i also intervied a student from diploma of commerce and she shared her exprince so that way the poster would look more intresting.for my background i used  grey colour  because black looks better on grey and makes it easier to read. I chose red for the title box because red is an effective colour. i also put the canning college logo to symbolise the school.
