Gallery design, a few notes
Don't have a sign so small that a visitor has to peer suspiciously into doorways and repeatedly walk in and out of porches to find your gallery. This is especially bad in a residential/neighbourhood watch area.
Don't hide your gallery behind steel gates, across junk yards, up fire escapes, or around dark corners. Just one of these is discouraging, all four are frankly a bit silly.
If your gallery needs this level of security because it is sited next door to a crack den make sure you, or your neighbours, have clear signage. Also make some attempt to repair bullet holes.
Don't have two identical doors, one of which doesn't open, causing your visitor to become so embarrassed at their botched attempts at entry that they hurriedly move on.
