Is 'The rest is for your imagination' right and natural? [closed]

Solution 1:

the sky's the limit (idiom)

Used to say that there are no limits and that anything is possible
"You can achieve anything if you really want to. The sky's the limit." m-w

As you consider all the possibilities it seems that the sky's the limit! ref.

On the other hand, if past events are any indication of future possibilities—then it is fair to say that the sky's the limit, that the future of science looks bright. ref.

It also ties in with your slogan Let your imagination fly.

Solution 2:

If you're looking for a natural expression that includes "imagination" but not "fly," I suggest either:

"I will leave the rest to your imagination" (very common - 10m google hits - somewhat cheeky-sounding) or

"Let your imagination run wild" (also somewhat common but pretty close to "fly").
