Natural Light in about 7 feet - Overexposed?

Normally the brightest spot in a picture is where you eye goes but the white is very soft I like the picture and a print of this will come out nice so no I think it is a fine exposure, bright but soft, the subject still pops out.

You could try and use the burn tool a little and darken the white a little and I mean a little just to see but I think it is ok as is. You might consider a slight bluring the sharp sand in front of and off to the left of the subject it is a ever so slight distraction as it is so sharp compared to the rest of the sand.

Any overexposure is in the negative space. The Tongue is perfectly exposed. This is where PS can really do wonders. Make a duplicate layer and add a mask. You mask off the Tongue and work on adjusting just the sand. Even if you can't get the sand dark enough, add some Gaussian blur to it and will de-emphasize it.

Did you shoot in RAW? If so, there is a variant to Scorpio_fish's technique that should work well, using 2 "different exposures", this one, and another 1 stop down...

I like the shot. The texture in the bright sand is still holding detail (except for the two small areas on the left half of the bottom edge), so I don't see any technical reason to darken it -- it's an aesthetic choice. If it were my shot I'd keep it rather than compressing the tonal range, or perhaps just slightly flatten contrast at the extreme high end of the luminance curve.

It's hard to be certain on a posted image, but my impression is that focus is sharper on the middle of the body compared with the delicate features at the head. This is also what makes the sand immediately in front of the beast so sharp (in my opinion, undesirably decreasing subject isolation -- but I won't start the DOF thread again!). I think a slight shift in focus (more distant) might have improved the shot. Unfortunately, can't PS a change in focus...

Again, nice shot.
