Here you go a scketch based on your brief where you can ask for any changes or make any suggestions. I think it's an elegant and modern tree and renewable arrows layout, that I think to be a good way to represent such actual business on these times... If any sounds promising, even after contest ends submissions are possible for the 1st ranked designer. Kind regards,
Here you go 2 more options with the same message; one with a more classical tree design and another with just a simp'le branch, a very good layout to be used in small sizes like biz card and be recognizeable cause it doesn't have small details that may look cluttered... All the best,
