It's simple,it effective ,it's functional,and there's no doubting what it's ment to represent .
So it'll get used.For me there's no better result than having what you make being used.
The time scale is spot on the longer you take the more chances the real world has to object to you relaxing.
As for meeting standards .You made it ,it works! For me All standards met and exceeded
In short great fun piece and I like it.
