Nice photos al!
A comment on the zebra in the trees. There are lots of photos where the unnatural placement of an object in a scene establishes tension and may cause the viewer to engage their imagination as to the back story or the purpose/message of the artist. If the photo is intended to bring forth the natural beauty of a scene, then the degree of authenticity is different than the case when a zebra outside its natural habitat (and perhaps with other props as well) is used to try and evoke something other than an appreciation for nature's wonders. It all comes down to artistic intent, which is closely linked to personal preference. In other words...Its all good.
My photo for the day is an electric clam (really!) The blue in the picture actually travels around the clam like a moving neon light.
