Hi, a pleasure to greet you, and is happy to be participating in your contest. Here I uploaded my design alternatives for your logo #24 #25 #26 #27 Hope you like.
If you have any requirement, please feel free to let me know. It will be a pleasure to work for you.
Thank you very much for your contribution! We do like your designs but feel the graphic perhaps lacks impact. The current leading designs make use of bright solid colour. Also, we would prefer the use of transverse sounds waves rather than radiating type waves like ))))). However you do not have to use the sound wave concept at all if you have other ideas :)
Thank you again. It is a great concept and we like the use of color in #31, but we feel the lines look a bit like tracks from a bulldozer, rather than sound waves :)
