Is this pic showing left hand neutral or strong grip?

[Burner]

Hard to really say from the picture orientation but it looks like the handle runs up the left hand lifeline and passes under the thumb pad, rather than nestles under the heel pad.

Also, the right forearm seems to be above the left, rather than under it.

All in all, the left hand appears to be strong whilst the right appears to be weak.

Back to the drawing board i.m.h.o.
