You have too much of an opening in the rear to create the inflow you are looking to achieve. Look into a balance enclosure filtered ductless fume hood. Something like this should get you moving in the right direction.
Everything is fine, you're great. But the ship hardly looked so dirty. (Although I do like the closely related "rat style"). It seems like the whole team has been having bad diarrhea for a month now.
Well it looks like it depicting her just after the Battle Of the Yellow Sea while she is running for Vladivostok. So she has just been in a battle as well as on active service for an extended time. So chances are she may have looked even worse in real life
Then the rescue equipment would not be in such an exemplary order... These are the objects that are the first to turn into piles of rubble in battles... But since this ship had no other outlets to sea (in this condition), I have to agree with this version)))
@BayinWu I saw this video yesterday and I was very moved. I mean, it connected to me on a deep emotional level. This is a great piece. Now I'm looking for a video of it in operation.
You can make display boxes from clear Perspex to keep dust off your dioramas .. There’s plenty of tutorials here on RU-vid for them if that’s of any help 👍
