Hello, pardon for a lagged in responding as I'd missed your feedback somehow..
Yes I would develop the concept further to give it a more technology feel (?) and in different colour as well. However, only the 1st ranked designer can submit revision now (the contest is in "Judging" mode). Do you mind temporary re-rank the design, you can switch the ranking back any time as long as you have not select a winner :)
Thanks!
