Looks great! Nice modeling on the glass.
Those bright splotches don't look right (I don't think I've seen anything
like that in reality). They may be a bug. Any chance you can email me
(or post) the code?
The reflective caustics do add a nice touch to the scene. 400k photons
is not too much for a scene (probably overkill for this particular scene,
though). I am surprised at the parse time (since that's basically spent
shooting photons) and the render time for that matter... how high did
you set your max_trace_level?
