I don't like that the icon is so much smaller than the text. It will work for a banner, but it is hard to see the overall design working in a square shape for thumbnail ads, etc.
I took the liberty to search for your site, I discovered that the background is black, and space for the new brand is more horizontal. If I may give you some advice, in the case that this site remains, I think it's better do not put other colours but leave this lovable stringency, using black and grey.
My plan is to shift my site from the current color scheme (and probably do a whole new design) once I have the new logo. I liked the black for what it was when I first built my site, but it is time to move on to something more brand-able.
I like submission #24. Anything you can do to make the icon portion more "3D"?
I like the text format of #28, but am worried the logo is too close to the Volkswagen "VW" symbol.
