As long a opening for makeup air is equal to or larger than your exhaust (duct) you are probably ok... Just remember any duct work that is part of make up air is part of your ventilation "system"... IN other words, length of fresh air duct plus length of exhaust duct equals total length of ventilation system...

So... Open window is probably fine.....

If you want to keep studio warm in winter and cool in summer you can route a large percentage of your make up air from outside (through ducting) to space between torch and wall and this keeps you from robbing studio space of heated/cooled air...

Also be aware any ventilation ducting the uses corrugated or flexible duct reduces the efficiency of a system be causing "static" pressure (turbulence) in duct....
