If you run it from the command prompt, you might get a more helpful error message.
The "\( -size 670x548 \)" does nothing. Nor does the first "-gravity NorthWest -composite", becuase there is only one image so far. Perhaps you intended "xc:white" or something after the size, eg "\( -size 670x548 xc:white \)"
