I really like this but the logo is too big on top. If it were able to fit in-line with the name it would be better. I actually like the Green and Orange.
I like your colours (and font) but the other designer's lightbulb is really nice, that's what has him in first. I've tried to apply your logo and the bulb is hard to work with. Remember, on the web you need to be able to fit a logo on a long rectangle, I like the square shape but it's hard to take a bulb with that much detail and make it smaller or just use as a stand-alone graphic.
