Mmm, yes, rich colours (I'm biased toward this; I LOVE rich, saturated colours in my own images). If you want serious C&C, post one or two images though. For now I'll just give a general comment; you need to use noise reduction. Luma noise is particularly detracting from second, third, and fourth images.
Bokeh looks a little choppy on the first too; that's a lens quality issue. More aperture blades will give you creamier bokeh. I'm guessing yours has 5-6 blades.
