"Finished" as in you're done but not really or had enough? XD
Your second one kind of looks like it's on fire but the flames haven't come over the top of the walls yet and the third one looks like a snowstorm, all pretty cool. I love how bright the beacon thingi is in the dark one.
I don't have a lot of experience with mist, only thing I can think of is maybe it needs to puddle a bit more, right now it looks like the castle is up so high on the mountains it's in the clouds :)
Haha right! I'll probably diminish the density of the fog but increase the contrast of it, to create perspective without adding too much "cloudiness" and make it look like a castle in the sky kinda thingy! Thanks :)
