I thought I'd post some senior portraits I took this past October here. I'm relatively new to the senior portraits thing since most of my work has been weddings. But anyway, here they are:
The post production is inconsistent, the first two are (imo) too sharp, the rest are a little too soft. I agree, more saturation in the color would be great, sharpen the eyes, and keep it on location, they're stronger images.
Other than that, they're fine.
The one smack center is a winner.
Overall, they are excellent...well done.
As mentioned, there are some processing issues which may just be in the hosting and posting. The first set did look a little flat to me...but many of the new set look way over sharpened.
To increase the contrast, I would suggest a slight tweak using Curves (Photoshop). Bring down the shadows (lower left) a little bit and see if that doesn't help.
