Entry #1 looks great. Could you change the "energy services" to black to keep 2 color, and swap the yellow and black in the droplet to see what that would look like please.
Also please change the "I" and make a bit taller than the rest of the letters. In the droplet have yellow on top and black at bottom with a thicker center line on the road. "energy services to black letters. Make those changes and we may have our logo!
#81- Can you make the droplet less fat at the top more narrow please. Can you return it to black on top and yellow under again like your #1 entry. This is likely the last edit and thanks for your help.
