I like your use of green. (I'm getting sick of seeing orange and black with all of the other entries)
#38 's font feels a little to "NASA-esque" for me. Although I want a modern feel, I don't want a futuristic/space-age feel. #39 's font is a little more appropriate. However, the icon portion of the logo doesn't quite go for what I'm after (fun, energetic, high-end party).
Thanks.
