That fireplace looks good!
Things I do:
-Most homes with an outdoors area, I make a viewing platform with seating so that you can get a good view of the landscape beyond the walls
-Fountains and water features often look better with some lighting (either candles or crystal lighting) below the water
Hmm, one thing I've loved doing with my statues is putting the dreamshards (blue crystals, stormhaven achieve vendor) inside them to give them a blue glow.
I put the wilderking braziers under ground so just the blue light is visible, going for that magical effect.
Plant a tree, use those ladders from the crown store and widest platforms from the normal vendor to build tree houses.
To make a stove, use a merchant counter, 3 stones, and 6 Breton torches. If you lay the Breton torches just right, you can have a gas stove with burners you can switch on and off.
