Can you work on the icon with maybe using a 3D cube as a starting point. Not convinced with the letter Q as it suggest the name is Qube Qube. However we like your concept so far really excited.
We love no.154 and 153, a few small changes and I think we have a winner!
- Could make the "qube" text the same width as the widest part of the pictoral, at the top of the cube - Could you also move the pictoral nearer to the text - Could you remove the shadows underneath the pictoral - Could you make the "Functional Fitness Training" text bigger, the same width as the "qube" text - so that it would be easily readable on a logo
