my last scene is one were both protagonists die, trying to disarm a bomb. how can i add some tension and make it dramatic?

ive thought of using close ups, dramatic music etc. but what else?

The best recent example is "Saving Private Ryan".

Spoiler

Miller dies after surviving everything starting with Kaserine Pass all the way through and including D-Day. But we see Ryan did manage to live a full life after he was returned home; he "earned it".
