QFN32 exposed pad stencil
I am no expert, but it does not look bad to me.
When you solder such a beast you want to be sure that all the pins will be properly soldered.

If you have less solder paste (per squared inch) for the EP than for the pins, when the solder will melt, it will try to wet the whole EP and will pull the QFN package, ensuring that all pins are close enough to their pads.

On the other hand, if you had the same amount of solder paste (or, worse, more for the EP) then you would have a chance that some pins are not properly soldered.
