I like your approach ie it is a little different to all the others. Prefer #1 as the symbol looks like sheets of paper - which is relevant to the ECM product - #2 reminds me of mountains and therefore not so relevant. Happy with the font
Is it possible please to use the other image you had that looked like mountains, alter it so it does not look like mountains, but still retains the refinement, and put it above the ECM360? Many thanks
