The coloration on six is a little over the top, but I understand that sometimes the client asks for that.
My biggest problem is with 5. From what I can tell, you took the photo with a small aperture (f16, perhaps?), then added the "depth of field" in post. This technique can work, but rarely, and never if they're being printed larger than 5x7. It very specifically does not work when the subject is not in the direct foreground, and there is any sort of leafy plant that you have to select and blur what's behind it.
What kind of lens were you using? If you're shooting weddings (and portraits at all, really), you need a prime lens. (50mm, typically either 1.4 or 1.8 aperture) I understand that it's difficult to acquire equipment when you're starting up, but a prime lens is well worth the investment. I know that Nikon makes a 1.8 that runs for around $200, Nikkor for around $100. I'm not sure about Canon.
