I think your entry one is still one of the best, perhaps you could make some minor adjustments and or refinements to put it over the edge :) .. I love your theme
Makinson I still perfer your entry #1, perhaps include a small oil drop at the bottom of the drill bit, work with color of letters and making your existing graphic stand out. That is the key here.. Your still in the top with your design, keep making it your own and steer away from what others are doing so that the design doesn't lose its character and unique idea.
Nakinson Entry 41 is AWESOME, I still perfer the darker colors as they bring more strength to the logo, and that oil drop in between was a perfect add. Work on you color scheme a bit.. and you will hit one out of the park
Makinson, use the graphic in entry 1 and the oil drop fro 71, keep the small oil drop between the name like 41 and use a green arc with a blue burst on the top of the drill bit. Make the big oil drop in the back ground with sharp black edges fading inward to give the 3D affect and try that please.
MAKINSON.. please use entry 41 and adjust you color scheme, BLACK oil drop, darker blue and a darker green. I still have a preference for that enrtry and the simplicity it has
