As near as I can make out from the exif info, you were on manual focus. I think for these type of shots, auto might serve you better. I think I can see what you were trying to do, but the focus appears to be elsewhere.
The potential is certainly there. Watch your composition too. There are poles and trees that are just distractions and don't really enhance anything. In fact, in one or two shots, it looks like that's where your camera was focusing.
May I ask what focus mode you're on? I use spot mainly, but that's because I generally shoot wildlife subjects. For wide scenincs, I suspect matrix might be a better option for you.
As for the shot of the cup, I actually think that's the best one you posted. It's sharp, and there are no distracting elements in the shot at all.
Don't get discouraged, Keep practicing. Before you know it, it will come.
And just a suggestion if I may. When posting, try to leave a space or two between shots. It makes it much easier to look at them and concentrate on just the one shot.

thank you
