tini1,
#27 Would you mind making the green a little bolder and switching the orange element to a rich yellow/gold (but not metallic) so that it represents the sun? Perhaps you could make the wind element green and substitute solar for the green leaf? So, to clarify, 1) blue = water (no change), 2) bolder green = wind, and 3) gold/yellow = sun.
Also add "Co." to top and "Engineering a better future" motto underneath? Thanks.
