Sexing megalechis picta?

Acquired a Megalechis picta not too long ago, it's around 3.5" now. I'm a little confused regarding sexing. I know the males develop large orange pectoral fin spines and have more closely positioned bony plates on the underside, but I cant tell if mine is male or female. The spines appear to be growing orange around the tips and the chest plates are about as close as those on my male Hoplosternum littorale... but I don't think these features are pronounced enough for it to look like a definite male M. picta.

Attached are some pics. Can anyone give me some insight on the sex of this fish?
Also, they just ate, which is why the belly looks so round here.

The plates are not even touching on pic 1, and that would imply a female.

Males have overlapping plates.
