Looks good so far. The only thing i can suggest is to add more previews. 2 or 3 renders but then also screen shots of different angles, on interior for me top view is a must and i never buy anything if i can't see at least a wire frame screen grab as well as a view port solid shaded view so in summery:
1. Renders (2 to 3 but more if the space is complex)
2. Wire frame screen grab showing different views but top is important
3. Solid shaded view - to check if there is any tension in the mesh which needs to be relieved with cut
Hope this helps!
