Over Exposure and High Contrast on Photo Thursday

I took some pictures of my kids recently...duh...I'm always taking pictures of my kids. They are pretty much the only subject matter I have...oh, and my sky!

Anyway, I did a few shots on a bright afternoon where I purposefully overexposed.

But then I went back into Picnik.com and did some edits.

I bumped up the contrast high, about 60% and then desaturated the color a bit. I was really happy with the overall effect and how it really brought out facial features.

Here, I increased the contrast again but left the color saturation alone and cropped it too.

I think this one was way too overexposed to work with,

 but I tried anyway.

This one of Yip I also boosted the contrast high and toned down the color saturation a bit.

I really like this effect but I'm not sure my kids are the best subject for it. I think it would have worked better on high school senior pictures or with an adult in front of a sun or really contrasy background.

What do you think? Are there any other situations where overexposing then boosting the contrast would be suitable?
