For crochet, this has a surprisingly a tighter stitch selection - perhaps to give structure for the floral motifs, which most appear stitched on.
It sounds like you are both interested in following this general look, but also going on your own. Both of which are cool! But what you dream would most likely determine your stitch selection.
The Malia Cowl has an interesting braid stitch I have used to give structure as well (e.g. followed by a more openwork piece), as well as an 8 count puff stitch:
I also like a braid laying on top to give some texture and pull the gaze: https://www.ravelry.com/patterns/library/goldenrod-sweater
I do not generally like fringe, but sometimes a motif is appealing, and I have a personal fondness for this edging (or to crochet, and attach scattered across one side): https://www.ravelry.com/patterns/library/crescent-moon-shawl-a
I DO really like the darker “grout” of this shawl (as opposed to the more popular white). To me, it’s very soothing.
I think it would be interesting to go through either your pins or your rav (if you are on there), and take notes as to what overall themes, stitches, etc. you are drawn to. Basically, profile yourself! And then work from there!
I’m excited to see what you come up with!
