Ar-Razaaq -- I like the idea behind #21. You have created a good minimalistic and pure feeling, and elegantly weaved in the element of forward direction. However, this design lacks the "advanced" and "innovative" feeling that I'm looking for. Perhaps you can use some sort of gradient 3D effect to achieve this. Here are some examples: http://www.1stwebdesigner.com/inspiration/30-logo-designs-using-gradient-3d-effects-inspirationpart-3/
Alternatively, our old logo (http://axeleragroup.com) may provide a good basis to build upon as well.
