LOVE the fonts... BUT we need to add a bit more Halloween as you mentioned. It has a very cool Scooby Doo type feel and I would not change the font but maybe try it on black and if you could try an icon of any sort like the eyes from #1, a tombstones, skull, bat...?
The direction you have works well but the event is somewhat dark and this is what is missing in your design... subtle change and nothing dramatic but I think it would make a big difference. It is a teenager to mid 30's crowd and they need to think it is both fun and scary which is why you go to a haunted house.
Great attempt and hope to see some additional work.
We like the new version on black and the addition of the art around the fonts help bring some "spook" factor which is exactly what we are going for. If you could try to reduce the imagery so that we have one main creepy or spooky factor that supports your font style or works with the logo we feel this will be stronger visually. Certainly do not want to rip off a classic scooby type monster but that style of art would likely work very well with your font style. We would like to have a "simple" communicative character or image like a skeleton, graveyard silhouette that can be incorporated into the logo.
