Yeah, I would have gone with:
Code:
____##_____________##___
___#__#_____#_____#__#__
_____#_____###______#___
____#_______#______#____
___####___________####__
Obviously would look better with proper spacing.
Edit: Hell, if you even make the sign one row higher and just bump the middle pixel of the top of your 2's to be higher, that might fix it.
