Bitch smack? Wow, that seems a little extreme, doesn't it?
Ah well, listening to the rendition you've got going here, it sounds like there is more source in there. It's not enough, still, but it's getting closer. I'd make the violin sound a little bit more prominent when it's in there - it gets a little drown in the mix, atm.
Let me give a percentage of source you've got going in there... 1:43 - 2:25 (42 seconds), 3:41 - 4:51(I'm not sure that counts as source, but it IS related, so I'll give half credit... 35 seconds), 4:51 - 5:48 (57 seconds) That's a total of 2:14 of source in it (2:49 of source if I gave the 3:41 - 4:51 full credit), out of 6:34 of music. That comes out to roughly 34% of the music that has relevance to the source (~42% if I counted all 70 seconds from 3:41 - 4:51, but that's not exactly source - it's heavily related, though). It's closer, but still not enough to sway the J's on the source usage. Harmony usage generally doesn't count as the source, by the way, as I notice you have a lot of that to try to cover that aspect.
This is a quote from LT (one of the J's for all the mixes that come through here)...
This is about as far from the source that OCR lets people go - it was a close call, for them (I'm glad it made it through - it's a sweet song). Source isn't important everywhere - just here at OCR. I'm not telling you this won't pass because of any fault in the music, I'm simply saying that without the source being prominent in the music the J's will not pass it, even if they really like it (and I'm sure they'd love this - it's very well done).
By the way, congratz on the #12 charts placement. It IS a very sweet mix and I personally enjoy it thoroughly, despite the lack of source.
