The good thing of that logo , is that you can use the cube seperately at anytime , therefore you can use it vertical , or horizontal . one for the website upper banner , one you can utilize for your business card.
as for its colors , it looks clean and fresh on a white background , so i do not think you will have a problem having it on your upper website strip on a white background right ? or on business card as well.
Any how , yeah i wanted to add the " i " as well , which you can later on use to reffer to the " internet " / online , etc and the " E " is the main as its the begining of your name
