Hi there,
78 is really moving towards what we're looking for! However we would like to see a few other options for the abstract markas, it looks a bit too much like a big J which favours one of the three directors initials.
We like aspects of each of your designs (includign the graph as it implies an improvement in performance).
As inspiration for you, we help companies to increase their performance in OH&S, Environment and Quality over time.
Thanks and good luck!
