The poster is clear and readable, but I do think it could be improved.
I like that the Introduction tries to provide a more organic look to some of the headings and images in it. But if you’re going to go that route, you have to commit to it. That weathered look isn’t anywhere else on the poster, so it looks a little odd. I would remove it to make the weathered paper and blackboard and the like to make the Introduction visually consistent with the rest of the poster. Of course, you could go the other way, and make the entire poster look more antique, but giving the rest of the poster that blackboard appearance will be harder and take longer.
I would generally try to widen the margins between the text and the boxes they are in. It looks like this is only have a fraction of an inch between text and line in some places. It’s particularly noticeable in the Literature Cited section.
Speaking of the Literature Cited, it is left aligned, as is the rest of the text in the poster. But because the text is so dense in the Lit Cited section, it makes the centered text in the Acknowledgements stand out like the proverbial sore thumb.
The INSPIRE logo isn’t centered in its box. Neither is the Rutgers logo, come to think of it, but because the Rutgers logo is an irregular shape, it’s less noticeable.
The mouse in the Methods might be flipped so it’s facing in, not out.
