Yes. Way too much post. Teeth ay too bright. Skin too soft. Eyes are good and you appear to have fixed the yellow cast. As for watermarks, yours is nice, but you'll find there are two camps on this and I'm in the camp that says that if you aren't putting something awesome up that you want to protect or use to promote you, don't screw with watermarks. It's almost humorous to see thousands of photos which aren't much more than snapshots with watermarks. And I don't mean this to sound rude, but none of those images look like something someone is going to bother stealing. I don't screw with them on the majority of my own work either for the same reason. When I do use a watermark, I make it pretty darned small and subtle so as not to distract from the image.
I am serious....and don't call me Shirley.
