Tell me what you think.

Honestly it looks like a rendered 3D model, not a photograph. Can we see the original?

Thank you for being honest!

(By the way, feel free to edit my pictures, I need to change that)

I have found that slight desaturation helps to diminish discolorations on skin. He appears to have yellow splotches on his face.

Not so much for this photo, but if you're looking for a professional look, don't use the camera's on-board flash. Or use it only for fill flash. For example, position him near a sunny window (but not actually in the sun) and use the flash to fill in the dark spots. This gives you two light sources, which can help to bring out the contours of the face. You'll have to check your manual for the camera settings for fill flash. Another alternative is a camera-mounted external flash that can bounce the light off a light ceiling or wall.

It's the lighting that makes it look like a snapshot...

These are usually caused by overexposure causing the red channel to clip. Looks like that here.

I'm really not sure what the OP was trying to accomlish in creating the plastic doll looking image from the original?

The point here is that the photograph needs to be reshot in better lighting. No amount of post production will make this a properly lit photograph.

See that dark shadow under his chin. Professionals rarely get that because they do not use the pop-up flash for main lighting. If you want some different takes on it post a bigger version and turn on image editing. You'd be surprised what might develop. you only need to brighten eyes when they are dark - in this case they are plenty bright because of your flash. You can buy or easily make a flash-bounce device that will direct your flash upwards to bounce off the ceiling (if you have a bright ceiling).

That was my first impression as well. Eyes are unnaturally white and look over sharpened. I don't mind trying new PP techniques and make photos look a little artsy, but this one is way too unnatural and pastic-looking. I'm not an expert on lighting but bouncing light around to eliminate that harsh shadow under his chin is a must.

It honestly looks like a quick snapshot. I don't think any amount of processing will make it more than that.

Actually, the original is a big improvement over the edited version.
