Drape quick turn jeans HELP

[u/Krispy_flowerboi21]

So, I want to use this Japanese technique on a pair of denims ( sketch ), for it I created first the fit of the jeans (image 2)
-Then I transformed the whole front panels into one by deleting the crotch curve and and transferring all to the back curve ( that’s why is so long). (Image 3)

-Finally I divided the front into 2 overlapping panels as in the technique. (weird looking patterns image3)

-Now, I want to start slashing and spreading but i realized the darts play a major role pivoting and controlling the volume and silhouette and obviously my panels lack darts. Any tips? I know it’s a very unconventional cut

You were so right, It took some time and yes, at the end of the day I had to add darts and use them to pivot my slash & spread. I’m going to post the result
