You can definitely get a few from the thread at the very least. I would PM him but I'm a bit chicken[censored] in that department.
Tbh I don't think I need the renders. Started work on Mario and his set seems to look great from just using the CSPs (:

I'll be continuing on the rest of the sets from now on, maybe 1-3ish per day, more if I'm really bored. SJS has made CSPs for all costumes in 3.6...EXCEPT Charizard's black armor. I'll PM him about it once BrawlVault let's me load a message without crashing lolol
EDIT: Finished DK and Link and uploaded to the same imgur folder. I'll work on up to Pikachu and then stop (Characters 001-008, the eight 64 characters) and then wait until SJS responds before going any further.
