BigK I thing photorealism-wise your Maxwell one takes the cake so far (kind of neck and neck with Thomas's then hdesbois's.)
Thomas your Vray one is absolutely gorgeous, Id say the prettiest of the group. But then again 14+ hours... ouch. (Well I guess that’s better than 19+ and 21+ hours).
I gave it a quick go last night, but I was going for something hopefully a little faster. Technically I probably don't qualify for this challenge because I didn’t render it with DOF, did it in post this morning instead (so add 20mins of total post time on that). Setup was about an hours worth of messing before bed and hitting render. It ended up rendering for a bit over 3 hours, but I actually rendered it out at 1600x1200 so I could do better post work on it and then resample it back down to 800x600 (to retain more fine details). Ended up using IR Map and lightcache. I suppose though that if I have rendered it out at 800x600 it would have been a bit under an hour. I made a mistake on the caustics though, forgot to change a setting, so they could have been better (chalk one up for a more simple setup program)
I did start a test with DOF and a more brute force setup and extrapolated it would have taken around 4-6 hours, but it probably would have been prettier. I also think the new adaptive PPT would probably do an incredible job in a 5-10 hour range, but then I don't have access to that yet (please render Gods give us 1.5 soon).
Anyhow fun challenge, looking forward to more.
P.S. Oh specs... Max/Vray P4 laptop @ 3.4ghz w/HT and 1gig ram.
