I think your illustration is great, stygg. I see much progression from even a few months ago, attention to detail, creativity that amazes me (the balloons with card suits on them? Too much, man! I love it!)

But logically (?!) let's ponder for a moment over the poster. You tell the audience where it is. But the sign sort of obviously begs, "It's right here!". So all you'd really need is "Grand Opening" and the hours and whether both genders are invited or not, and whether there's a live band.

You don't need to put the location on a banner if the event is right there, correct?
