I think some of your stuff is great. Particularly this (but the original image is nearly perfect as is!!! Is that straight out of camera? Wow!) I think this is a great example of what retouching *should* be.
Others, I think you need to watch the colors as it can tend to look a little "clownish" to me. The background color here changed in your edit, too, which sometimes happens when messing with color correcting, etc. Not sure if that's intentional or not!
