Basia, Bangsy, mixed conditionals and other stuff

The other day I was talking to my niece Basia. We were sharing thoughts on Bangsy's graffiti art as well as on a handful of facts - and missing dots - that his bio consists of. We enjoyed exchanging ideas on the possible meaning of some images, and the messages incorporated in them, too. 

The next day an idea dawned upon me that, among countless ways of inspiration, Bangsy's work (or, Bangsy himself, for that matter) can give us a hand at practising mixed conditionals.

So, here we go: try to translate the sentences into your native language.

If Bangsy hadn't painted all these graffitis, would the world be the same?

Would Bangsy be so well-known if he hadn't decided not to show his face or give interviews?

Now, let's speculate on the graffiti in which a girl has let her red heart-shaped balloon fly off:

Would she still have the balloon if she had held it tighter?

If she had kept it for herself, would other people be less happy?

If she had done it purposefully, would she regret letting it go?

If she hadn't done it on purpose, would she like to get it back?

If people knew such actions make a deep sense, would they have done more of such symbolic acts?

If we had acted out of our hearts more than of our minds, would we live on a happier planet?

What would happen if we dared now...?
