It is not easy showing your work for criticism (constructive hopefully), so congratulations on doing so. It is also not easy given the modern set of tools we have at our disposal these days, not to push the enhancement sliders all the way to the right or left.
My advice would be to use moderation and aim for subtlety in tones and hues and a good way to do this, is ask your partner or a friend, to look at the before and after images on your screen and give you their (honest) opinion as you sit quietly and let them.
My wife does this for me and even though I did not want to admit it at first, as she is not the least but interested in the technicalities of photography, but invariably she is always right and I always take on board her advice - it looks to blue, it doesn't look real, you have been fiddling with the colours again haven't you etc etc. So when she says things like, Ooh now that is beautiful, or yes I like that one etc, etc, then I know I on the right track.
Only a tip that works for me, and I am in no way saying that you need to change what you do, but you will be amazed (once you get used to doing this without arguing) how useful and good the other person's advice will be to you, even if they have never picked up a camera in their life.
