Hard to tell, looks pretty good, but now I'll be really nit picking as it may help you see something subtle...
Right limb a tad stiff on the last (tip) third.
Left limb, the merest possible shaddow of a hinge where that dark branch in the background goes behind the limb (or maybe the branch causes an optical illusion?) Then there's a slightly stiff section to the 2/3 mark.
It's always very subjective.
Like I said, overall, looks pretty good.
