Like where you are going, I have a few comments and suggestions. #51 and #53 looks like falling apart instead of coming together, #19 feels more like something is coming together. The concept we would like to communicate is chaos becoming something organized or many parts becoming a whole and i think you are going toward that idea. Would like to see you try #53 but instead forming a square, form a building or buildings (we are about creating and managing the information and infrastructure to make a building run). That's just a thought. We also really like #55. As far as colors, we like the blues and greens in #53 and also like the orange. Keeping going brighter. Also try using shades of grey and not so much black.
