#12 - I like the layout. But I prefer to use more gray or black. Also don't know if we need two leafs.
#8 - I like this layout. Like that it has buildings. However, I'm not sure I just want skyscrapers in it. Would be interesting to see how it looks with another kind of building symbol.
#5- I like the colors. The design is a little plain.
#6- I like the industrial look of the gear in the circle. I like the colors. Think the top may be a bit too faded. It's not really clear that the buildings inside of the emblem are actually buildings.
I also like how the color of JOULE is more solid,dark, green. Very nice.
Thanks for feedback! In #8 it is supposed to be growth bars (like profit, etc.) but could also be buildings. I can put a building shape in there. Anything you like about one design can be combined with another, same with colors. Feedback helps, thank you!
FYI, it is against LT rules to ask for an element like a gear introduced to a contest by a designer when it is not part of the original brief. That is the only part of this that I am claiming as my own concept. Designers try to respect each other in this regard because we have to compete every day in many contests. Thanks for understanding.
