I really like this. I love the asymmetry of the design, and the elements are great. I also really like the fonts. I am on the fence, because the box feels big and maybe a bit heavy, but I am not sure it would be improved with a smaller size up top.
Maybe if it was a purple line perimeter, not solid?
The problem is that with letterhead, or on the website, I have to keep the whole logo pretty big in order for the text to be readable.
