For 54..........can you get rid of the ties entirely, so that it's 3 solid figures (1) and then a second design, fill in the ties, and for the middle Cylinder, have it checkered with blue and white little squares.
Also, the reason we liked the other design is b/c the symbols are actual database symbols. Maybe there's another DB symbol you can incorporate in to the design instead of the "people"
I love the work so far and look forward to what you some up with next
