Love that you worked through observations and flaws in the previous design and made them tangible. Love that you simplified the “Who is this? Where is this?” Love the thoughtful use of the protruding 1” of the A4 in an intentional way. Slightly biased that you had the pen pointing to my talk ;)
Next, re-design the sponsor table configuration on the mezzanine and the way finding to mitigate all the traveling traffic between talks. THAT was truly painful.
