I can't judge the Original version, yet the one you've created in english... well I can understand what you write about (in terms of language), but there is quite a lot of misleading informations in what you're writing. To me it sounds like you don't know too much about HDR and wanted to sound technically - well this probably works for others that doesn't know anything about HDR in general, but...

I will select like 3 random things to comment:

• What is the difference between a HDR and an image?

HDR is technique, image is... just an image. Outcome of a stacking few exposures is also an image so there is no difference there.

• Tiger example

This tiger example is not an example of HDR technique - just simply raising contrast ratio. You don't need HDR for that.

• Tonal range.

It's something different than a Dynamic Range. You might have high Tonal Range but low Dynamic Range. As you're trying to explain at the very beginning - Dynamic range is an ability to register at one time very bright and very dark areas. It is separated from ability to register colour. For example human eye has great Dynamic Range, but lacks tonal information in low light.

Anyway It's nice that you're at least try to explain difficult things to other. Don't take this comment wrong, take your time to analyse and understand the topic you're trying to explain others - this way you will create more valuable content for all of us. Everything the best for you.
