Maybe I'm not looking at it right but there appears to be a sink above the sink?
Also, it should be "my juice tab" and "can you help me pay my tab" since tab refers to one cumulative debt.
Also, what's with the empty bottles in front of the guard on top, shouldn't he have some frosty mugs (or empty mugs) in front of him?
Also, a bridge tile might look more like one of those upward swinging tops for the bar table than a signpost?
I didn't actually come here to nitpick though. I actually like the screenshot and the overall art in your game. It's better than my pub. :P
