Notable unused logo concept | ( for sale )

Hey guys,
here is a logo concept that didn't make the cut for Notable, but I really like how simple and bold it looks. I know I have posted yesterday a shot that include this concept, but I wanted to make another shot with this concept alone, and maybe we will find an owner for it.
Happy to hear your feedback about this concept and if you have seen something similar done before with N letter and exclamation mark!
