Hi, the designs you made are to simplistics. Here some directions you could use :
Make some amalgam of letters drawings with the BI letters. Try to move the drawing to another place by the BI SHAPE words to see the effect.
Add some 3D effect, some depth to letter, some reflection on the ground or other drawing.
For the font used for BI SHAPE, try something more "futurist", "terminal" or "computer based".
The colors are good.
