Bighorn

I would crop off the bottom to get the animal lower in the frame. And then I would add contrast to the plain and add saturation to bring out those oranges and purples. The image at this time looks a bit bland, perhaps due to harsh light.

Great subject. I think Igor gave some very good suggestions. 

Wow, doesn't look like it has lots to eat there!  Death Valley is such an intriguing place to me and most images I see here are more intimate landscapes, so I really appreciate this view.  Hope to make it there one day.

I think for images like this to work the subject needs to be turned to the camera....
It has a nice feel but lacks contact.

Harley,

A great moment to have experienced seeing this guy in DV.  I think you did a great job positioning the sheep in the frame; yeah, may not be turned in to, but at least turned in to, and facing in to the frame.  You're right, he's pretty much an accent to the landscape, but most certainly adds a great element to the nature story here and it's much more than a landscape with his presence.

It's the story that I'm responding to; the presence of wildlife in such a harsh environment. Sure, I think you could tweak the processing in the landscape and wish for later light, but I'll take this just as presented.

Harley, It's always nice to see environmental shots with animals within the grand landscape. Yeah, the lighting is harsh, but it does tell a story. The horizon line between the playa and the mountains in the background definitely seems seems tilted down to the right, although strangely enough the ridge the sheep is on does not seem tilted. I would suggest rotating this one counterclockwise to level out the horizon in the back a bit.

Due to the harsh light, this image might be stronger if converted to black and white, although that would take away from the environmental story here.

The triptich nature of the view is striking, Harley.  It's also fascinating how important that tiny sheep is the overall image.  It would be a good graphic view, without the sheep, but her presence turns this into a statement about life in the desert.
