I quite like your submission - especially #8 and #9. The sideways S which also looks like infinity symbol is quite good. double S allusion is good too. could you try it with some green, ie - graphic element orange (as u have it) - Seagull = green - Systems = grey (as u have it)
Also, I think graphic element has to be on same line, however in #8 it seems to be relative to the text.
