Looks okay to we -- with the exceptions that in this trivial example, there is no apparent reason why the static method should be static, or even be a method at all (it could just be a class property).
On a side note, I almost never use static anything. About the only exception is the (very rare) case when I make a singleton class, in which case the method that returns the object needs to be static. (And I can go for months or years without creating a singleton.
