This logo concept is quite different from other designs of the same letter. If it was to be shown from the front, you would only be able to see the line in the middle, where as if moved a little to te side, the flat sides show up.
I feel like if I think about it too long, I want to say it's not easy to read. But then I realize that I knew what it was as soon as I saw it, so obviously its working. Being recognizable is very important.
This is a clever logo which uses negative space to give dimension to the letters. The H is hard to see at first and forces the observer to look at it for a while until it appears. The use of shadows and tone makes it look professional
