A very appropriate logo to comment on right after Halloween...
I agree with the comments that the font is hard to read (I'm not sure I would have read it as Afterdark if I hadn't known that that's what it was supposed to say).
However, the design CONCEPT is nice with it being incorporated into the bat, and the second color combination is much better in terms of readability.
One thing to keep in mind with any logo is that it should be readable wherever you'll use it. Seems obvious but I've seen plenty of logos that look great when they're a few inches across (i.e., when they're being developed), only to become totally indecipherable when reproduced on a business card or as a small logo on a web site.
I'd most definitely play with that font and even toy with making it much bigger to fill up more of the bat shape.
Have fun! :}
