I think the 2nd set of photos are vastly better, if only because you can see the end of the kitchen where you'd sit and it looks really nice. In the first set of photos it just looks long and dark like a corridor.
So #1 get rid of the first listing and stick with the 2nd one.
Keep the outside tidy
Move the beds in the two rooms where they're tucked into corners, so that they back onto a wall and have space either side for getting out
Move the L shaped sofa slightly more into the room, so again its not backed into a corner
As an aside I absolutely love your carved chair and love-seat - gorgeous.
Also consider re-listing it with the 2nd set of photos but under price it slightly. you will get interest and then competition which can push the price up.
I would resist it as 700-750k to be honest, and that's mainly because you'll have noise from the motorway. I would also include that in the description - "conveniently close to major roads"
