I like it, and I like the typeface you’ve chosen. It has a nice, warm quality to it that, I think, works well.
I have mixed feelings on the different logos on the top row, but I’m inclined to like the two solid black ones better than the outlines.
As for the compositions with your long name, I think they work nicely with a professional corporate look (if that’s what you’re intending). The length of your name doesn’t bother me at all. My least favorite is the last one where you’ve placed your name on two lines and centered it.
I see no purpose in the period after graphic designer, however. It’s not a sentence, so the period is not needed and is out of place.
Even though I like the logo, my mind does have a slight tendency to see the D and the O as the numeral 2 tipped on its side. That just might be me, though. If you tipped the logo upside down, however, it still reads perfectly as a D and an O, but the numeral 2 illusion is gone.
