I like your use of color and abstract images, and that you included a home in the image (since we're a home care company). However, I want the main focus of the logo to be the words "The Power of More" with no reference to "BrightStar" (although feel free to use elements of our company logo like the red star or yellow "swoosh").
I just uploaded our previous conference logos to my flickr site: www.flickr.com/becky.seiler/
Those should give you a better idea of what's been done previously for past events so you can come up with some "The Power of More" examples. I'd like to show a couple of options to my CEO tomorrow or Wednesday, so I'm really looking forward to seeing your other designs for this logo :) Thanks!
