I think there are both effective, although the second is the stronger image I think. Is that mist or smoke in the first? Actually I rather like that it is not clear which it is: in there second it looks like both!
In the first image the band of mist / smoke creates a sense of mystery I find and one wants to know what it is hiding.
The second is more conventional I suppose, but you have resisted using a large depth of field and the layers of focus work perfectly I think as do the layers of focus.
