Love the colours/light etc is 45-47 etc. Your font and proportion is the best. The triangle does not really relate to anything that we do though. Perhaps some cubes/building type shapes?
#83 is great. The three blocks represent buildings. Ca we take a look at; - varying heights for the 'buildings' - play with the swirl that goes around the globe.
The lower globe make me think of 'upside down hat'!! I like the 5 buildings - what does 4 look like? (2 centre ones tall, outer ones smaller?)Still probably prefer the imagery of #83 - though not quite there
