The sample change with the hats was excellent, and the bass drums are not nearly as harsh as they were before - Nice touch . I'd be careful when you double the bass at some parts, though - it tends to clip the sound a bit, then. Put in some velocity work with the drumline and I think the drums could work fine.
The piano sample doesn't seem to fit well with the other instruments in this song. I'd replace that sample as soon as you can (the same goes for the guitar, but you knew that already ).
I like the harmony work with the choir - I see we've been working on chords and such .
Careful when mixing levels - some instruments seem to shoot out of a quieter texture, which is jarring. Make the levels more homogeneous and you'll also be able to raise the volume of the song without clipping, so try to balance the levels out.
It's getting better, that's for sure - you could make it better still, though. Best of luck!
