I see you working with those synths, good work!
for the bell sounding lead, I'd make it on the space and give it some of that metal detuning the synth offers. then you can route the tuning to an lfo to give it some slow vibrato. Also, I'd take the main chords that have the melody and mute them out some to bring out the warmness of them. maybe lower the filter to about 100 hz at a 12db slope and automate it with an env with a bit off attack, long decay, mid sustain and a little release.
