My question was what kind of problem you have. If you were seeking for instrumentation advice or mixing advice.
So, mixingwise, the biggest difference is the reverb. Go for a long reverb and boost some lows in it to match the real recording. Also the double basses call for increased deep end. (Did you double the celli with double basses one octave lower? If yes, rise their level quite a lot.)
Yes, in the ending brass try a Tuba, but also try the trmobones one octave lower.
Decrease the high mids of celli and horns, eqwise.
