It was all a bit of a rush at the time. I too like the composition but feel we could have pushed the realism a bit further, knowing what Maxwell is capable of. One thing we learnt from the process was not to use a low quality IBL - the one used was off one of those holiday web booking sites which was only a few hundred kB in size but had the right location for the project! I was impressed though, with Maxwell's ability to still "pull out" subtle lighting from the image which was the only light source for the render.
....enjoy your Christmas
