I think the graphic element used in both of your concepts has potential. You could try some gradation to give it more depth. Also, if the green elements have a leaf feel and the blue is more like water droplets, there may be some possibilities there.
I cannot upload any changes nor new concepts, because your contest is in Top 5 phase. In this part of your contest, only the first 5 ranked designers can make new uploads.
We planned to give all the remaining designers a go at revisions, so I have bumped you up. Feel free to submit some new concepts and revisions based on my previous feedback and the comment I left on the main contest page...
"The graphic element must be able to stand alone and be well-balanced without placement near the name. For example, if we were to place just the graphic element on the back of a business card, it must be visually appealing enough to sit independently. Also, while we are fans of abstract, the shape itself need to be interesting. So, random is OK, but it must be appealing."
We look forward to seeing what you can come up with. Thank you!
