Just be aware that the egde-crease modifier most likely wont be exported in case you ever decide to render your scenes in a different render engine outside of Blender.
On the modeling side of things I am course willing to help, but everything seems very fine to me. What could be improved are the two towels. maybe apply (bake )the cloth modifier as it is now, subdivide a couple of times and simply sculpt over them. Should not take too long IMO.
What I did for image aligning was a bit of a pain but proved to work quite well to my surprise once I got it figured out:
1.) Get a copy of 3DSMAX trial and sketchup pro (?) trial
2.) Align scene in Sketchup and export to .3ds ( that should include the camera positions)
3.) Open scene in 3ds
4.) Get the scripts
http://www.blender.org/forum/viewtopic.php?t=17168&sid=3bd6896ffa9be3121ce142f22e941432 I sticked to the Blender 2.52 version, the newer ones never reliably worked for me. Run the 3dsmax script ( it says only 2010 but it worked at least up to 2012). That exports the scene and cam data to a format Blender can read.
5.) Get Blender 2.52 and install the script in the link. This will give you a button under the World or Scene options ( sorry doing this by heart) that says import scene. You select the scene you exported from 3DSMAX and voila you get the cam data in Blender.
6.) Since 2.52 is pretty dated and very unstable I suggest you open your nice and new 2.64 at the same time and paste the camera location and rotation and FOV values from the 2.52 scene to a scene in 2.64. This will give you all you need.
7.) Open up the image of the filed scene in Blender and press Z for wire frame mode. Ensure that the FOV is right as you need to manually tweak it a bit. Rotation and location are always matching though.
8.) I then split the window in two halfs. one the right I stay in wireframe mode to ensure that stuff matches up. On the right is normal 3DView with regular shaded view.
This might sound way more difficult than it is. Once you know what these exporters do it does not take longer than 10 min at best. But really paste the camera values and do not work with the imported camera. I got really weird termination and Z-fighting errors using it, esp. with AO turned on.
