design isn't just about making something look pretty. It's about conveying a message that is aesthetically pleasing. What message are you trying to send?
The typeface doesn't exactly portray professionalism, so like others have pointed out, I'd try some others. Also, with the way the text is broken up (by the "ground" line, the white bar, and the wings), it doesn't quite read right.
Oh, and I might be alone on this, but I'm not a big fan of how all the "stuff" is in the middle, and there's nothing going on in the rest of square. I think you could space things out a bit more so that the center isn't so cluttered. Just a thought.
And lastly - why is there a white dot/rectangle to the right of the tree?
