well the tagline and DVA can always be rearranged when getting ready for say business cards, web design etc.
for now its just an over all look and feel, rearrangement is the easy part
I'd say that the name of the company is very important. And part of the look and feel is the font choices.
I think the logo "mark" itself is okay. But like Virgo I would be very concerned for you about the company name, not only the size and proximity to the mark but also the choice of font. Your mark above is clean and nice, and you chose a serif font. It seems to be at odds to me.

Try stacking the company name underneath the DVA. This would allow it to be a little larger in font size and keep it in balance with the rest of the logo. Right now it's too small in comparison to the other logo elements.
Also maybe work the logo mark into the DVA somehow making it one unit rather than two separate entities on top of the company name.
The design field not regulating itself is a big problem. I've quit freelancing because there is so much competition from high school kids sitting in their parents basement using pirated copies of Photoshop...
