Week 2 poster1 with color testing

The poster belows has  different layout. 

The tutor suggested that the larger-size text does not associate with the small text well. It kind of squeeze the small text and form a a kind of sharp which doesn't fit. I think i should either fix it or change the layout completely. 

The poster above is the one i adjust after the tutor critised on the class

I create a different layout on the page. (Poster 3)

I also change the colors and the text seeks to create a different hierachy on the page. 

The posters bellow are samples using different color with the same text on poster3 above. We were suggested to use either dark color on the text with a light background or a dark background with bright text. From where i stand, Some poster below with bright colors does not suit the theme(archietecture) of the poster.
