It was designed and made in two days... could be better (always). I used a colour wheel to select the colours and made use of the “circle draws attention” trick I read in a book and also read in one of your posts.
Sokartis’s deliberate consideration of the use of colours and circles both pay off. Both features work very well. I would have tried making the position of the “callout” circles more consistent. The two left circles just don’t agree on a pattern.
There could be two ways to achieve this. Either you could place them all in the upper right corner:
Or, you could place them all by the margins:
I slightly favour the third of these, but the difference is minor.
The other thing that you might see in my mock-ups above is that I tried to make the blue boxes the same width as the others in the column.
While I’ve stated before that a reader should be able to follow the reading order of a poster without arrows, I don’t mind their use here. I think it’s because apart from the very first transition from the “Premise,” you’re simply moving down the page. The brush strokes used for the arrow bring an nice organic touch.
The only other small thing that comes to mind is to remove the underlining from the headings and author list.
Finally, this poster benefits from simplicity. It has very little text. It has clear highlights in the circles to help browsers through the poster quickly.
