I like the mood you have captured, in the 2nd at least. If you don't me saying though, a few tweaks would improve a lot I feel.
1: If you could move the mountain in the background, just search Google for "Terraforming Tutorial"...alternatively, face somewhere where the sea goes on and on to the horizon...
2: Stick a nice chilled bottle of wine, and a few glassed on the table. Loose that ashtray!!!
3: Try and time the shot to include an element of Sunrise / Sunset...
Cool stuff!
