Hi William
I have really mixed feelings looking at the first set of 3, my initial reaction on seeing the thumbnails was ooh, this will be good, nice subject, good b&w conversion, I will like these but on clicking to enlarge I am disappointed with the post processing, i think it really lets down what could be great images. I notice that nobody else is picking up on this so take it as my over critical view but there is no transition between the sharpness of the centre and the obvious treatment to the surrounding areas, it's really off putting and detracts from the image as a whole.
These are nice enough views to warrant reworking the post in my opinion, I think it's the blurring that bothers me, the subject is already in the centre, maybe a heavy vignette would work better than a false out of focus/gausian blur layer? Whatever you do, as long as the processing isn't so obvious it will improve things, it's possible on the first shot to draw a circle around the zebras where the sharp changes to blurred and that really bothers me.
Sorry if I'm being a bit harsh, I wouldn't bother if the image wasn't worth it.
