Here's another horse shot. I am really pleasantly surprised at how good the bokeh (very smooth) is on this lens for a variable aperture telephoto zoom.
Dustin, have to ask you...how do you get such nice/soft tones? Love how you process your images! 
That whole workflow was all within Lightroom (4), so no Photoshop there. I have invested in some presets for LR that I further customize. The basic look is from a preset collection (
http://www.adobelightroompresets.net/lightroom-presets/ultrafaded-presets/) Preset 9. By the way, these preset collections often go on sale for 50% off. I then further tweaked the tone curve to bring a little of the low end back, used a preset brush to paint in a little sharpness and contrast to the forelock. I probably tweaked the sliders a hair, but I doubt that I have any more than about 4 minutes in processing this particular image. Another collection I use a lot in my workflow is the "Instagram style" presets. I usually customize the sliders somewhat after processing, as I am pretty familiar with the way that LR works at this point. I typically spend as much or more time in adding metadata, descriptions, and keywords as I do processing. I am careful about all of those things because a fair bit of my work moves commercially in one way or another.
