Hi again, just talked to my Board member who prefers #208. However, could you remove the leaves from the chimney and replace with 2-3 small triangular chasing arrows leading into each other like smoke would (kind of like this:

Or, for #217: instead of leaves, use stars (kind of like this:

No idea how these ideas would look but worth a shot if you have the time!
