perhaps the smoothing was a bit too much as it's a solid blue so I would remake that bit more efficiently.
I just quickly did this to give you an idea of what I mean
Base mesh something like this although this was done in a few seconds so you could make it a bit nicer
It will look like this when Smooth Mesh Preview mode is used in Maya 2008 (press no3 key)
Then convert the mesh preview to poly's using linear and it will look like this
Should be more efficient.
