over all idea is nice, font in second iteration of green one is better, i think some text alignment can be tweaked a bit. The glass effect on O can be removed i guess, plain text should look nice.
i like it its good, however i would recommend changing the font on the bottom, looks childish to me good luck
The version with the Big E looks like an early-90's logo... What's the site about, so we know if it's gotta be trendy or business like.
first one's the best by far. thw only issue is the other weird brush script font for the tagline. Unify it with the font from the title and you're set.
I think the old English style E is nice, but the logo may look a little better without the drop shadow, in my opinion.
I think it's way too big. Unless it's going on a splash page (which are useless) I'd cut it down a bit.
