Ino, sorry I just realised you had two different designs here, apologies, the first comment is in reference to design #1 and #2.
With regard to #4, I think this also has huge potential. The colours in the symbol are not what we want, and the centre of the symbol has us thinking that the symbol looks slightly like sweet, so, if there was a way to give some unusual and deep/strong dimensions, like a 3d geometric shape, say an octagon, just for example, you could perhaps work from there. I really like how this creates a sense of what our company is about. Thank you for considering carefully what you design.
If I am unclear on anything, dont hesitate to contact me,
Again, thanks,
Almatious.
