It is clean, very easy on the eyes and looks very profession. Great Job! I do agree I do not care for the gray, but if that is the logo you currently use I understand not wanting to change the branding.

It looks nice and professional, though quite standard. I don't like the font you chose, looks kind of "microsoft 98" old.
I also like the building shadows at the bottom, however the grey building at the far right doesn't look well.
