Aye, shadow-mapped lights always have a more video-game like feel to them than ray-traced lights. Just my opinion, I like the stark clarity of the C4D render, but the Bryce render is definitely better-lit. I DO see a greenish tinge to the C4D render, I'm using a Viewsonic E771 which has damn near perfect color. Perhaps there's a bit o' green in the material mix? i don't know C4D at all...
