i’m alway the kind of guy who has way too much to say, so don’t shoot me for it :twisted:
i think you should first do as much as outlining the model like the first stage you done. Don’t even think about the subdivision of the sphere and about the rivets and bolts. This is just detail.
Although it is steampunk and the realization is not important, let’s think about the functionality of the think. First i would suggest the propellers in almost all directions. You could put the propeller even in a short broad tube with a fan to close it. This would give you the opportunity to create other smaller tubes connecting the fan to the dome as of applying steam to it from exterior. This will be just to appy some detail.
Then you could create maybe 4 smaller steam-blowers around the fan in all directions as so the dome will be able to go any direction. It is in space afterall Or now i think about it, maybe the bottom is just enough, but let’s keep the propeller in all directions
Now these “suggestions” are kind of my idea to be able to afterwards create a more random and fun subdivision of the dome like in your drawing. At the moment it is too grid-like and the big bolts make the scale of the dome a bit too tiny.
Cheers and remember to do with my comments what you like It’s just my thoughts on it.
