I'm going to be frank (=brutal) with these since I think you can take it and I know the excellent quality of your work.
#1 - the B & W isn't punchy enough so all you get is a black blob of trees on the left, rather than trees and shadow. Needs more PP to push the contrast more. Maybe the shot isn't worth the effort.
#2 - Great capture, but needs a bit more saturation and contrast to make it zing. The image is of your usual high quality, but the PP lets you down.
#3 - PP again I'm afraid. The CP works well, but the image as a whole is too dull. The trees and water need to be more vibrant. This has the makings of a "tourist brochure" shot, but neds a pump in saturation and contrast
#4 - Perfect - The PP is spot on as is the image. Great lines and the birds sitting along the top really MAKE the shot. One I'd love to see nice and big and framed.
1 out of 4 are great, 2 of the other 3 have strong potential waiting to be realised.
Of course read the disclaimer in my tagline

and apologies if I've offended you
Edit: Looks like you made the right choice it's been drizzly and overcast in the Hunter most of the weekend.
