Gruetzi Elysia!
I see Death as an ending: it might be slow in coming, or it might come at you fast, but either way, something ends - a job, a relationship, a way of life, living in a certain house, a season, a holiday, studies, a happy time, a bad time, an illness: when the Death card appears, it ends. Something else will grow in its place, for out of the seeds of Death comes new life. The process from Death back to life can take time - or can be simultaneous (like when you get married: at the same time your life as a single person dies, and your life as a married person begins).
The Tower, on the other hand, breaks something up, or shakes it sufficiently to shock it. It is often unexpected. It can signal a sudden realisation, a sudden illumination, or a sudden event - happy or unhappy - that will strike through a situation or person that was locked and generally stuck. That is the reason it comes directly after the Devil, which shows imprisonment. The Tower effects the liberation, and how it affects you will depend on how attached you are to your prison, how much you fear or embrace freedom, and how stuck the situation was. It can be a shock physically, emotionally, mentally or spiritually. It can wake you up - and its best, it shocks you back into the flow of life. Generally, it is a bit of all that. Sometimes - often - it also means there is a Death, an ending: so Death is "embedded" in the Tower. But the Tower goes further, and the focus is more on liberation than on endings.
When time comes to build up again, you have a pile of bricks, some of which you will be able to reuse. If you've learnt the lesson of the Tower well, you won't build another prison for yourself with it, but instead, a bridge.
