Too much similarity to a recent presidential political logo with the circle and curved stripes. That is not the association we want to make. It seems to have too many gradients and highlights, etc. The mark is only shades of blue, not other colors. It's very clean, but too "techno" looking and the icon is too dark, busy, political.
#28 - the "environmental" in our name does not convey "green" but is a reflection of the environmental testing equipment - particulate testing for laboratories, etc. So the green leaf isn't really appropriate to our industry.
