kgosden those mountain ridges look really cool & the ducks were a very good spot. Yellow bird is good too but I just find myself wishing you could have positioned the bit of green background behind the bird to separate it from the background a bit more (being very picky now sorry).
Raven maybe it's just me but I'd say your recent shots seem to have more vibrancy is that an effect of the 620 or PP. That last set are very nice but my favourite is the flower one. I really like the colours & DOF effect.
