Clean lines, creative, shows longevity
simple but creative, attention to detail
It is not mandatory but myself and my team would like to see some logos with gears included. However, it is by no means necessary, you can be completely different. We want to see your creativity!

Unless however you feel it fits the design well, in that case go for it :)
