Well, Clockwork, this isn't very helpful as a comment and some comments are better only just thought up in one's head but not expressed in words ...
... but anyhow: to me, these photos look every bit like a newbie first testing out the effects of shallow DOF with a first DSLR. Which is justifiable, since that is EXACTLY what you were doing! You are enjoying the possibilities your camera is offering you and you are PLAYING with it, testing out all sorts of things. Just the approach to take ... though, of course, little of what comes out of the testing is really that show-worthy in the end.
But I see ever so many photos taken by newcomers to the hobby testing their possibilities for shallow DOF and blurred backgrounds, and enjoying the effect and the bokeh they get.
But for future tests remember what RMThompson is telling you: choice of DOF is meant to put the focus on your subject, and not to a random middle part of your photo.
I'm sure you'll get there. Never stop playing and testing and thus learning how to use your camera best.
