You need to be aware of DoF, it's not as simple as one setting, unfortunately.
When it comes to processing style, find something that works for you and stick to it. There are several different 'looks' on the shots and on your earlier stuff even more. I'm no great photographer, but if you look at one of my blog postings you'll see how the shots work as a group in a way yours don't. I use the same processing method for all my shots.
You really need to understand your metering, it's obvious to all the photographers here that some of those shots have been pulled and some have been pushed. My usual method is to lock exposure on a neutral area and shoot AV. Shooting AV gives me fingertip control of the DoF and locking exposure is quicker to me than shooting M.
