What a fascinating idea:
Sigrun - pine, musk ambrette, bergamot, vetiver, oakmoss.
Mikkel - oakmoss again, clove, thyme oil, bigarade, cedar bud, and one of the really rich green notes. Maybe galbanum, basil and myrtle. Vanilla?
Emil - sandalwood, of course, and maybe musk. Basil. A sharp bright green note, maybe rosemary? Patchouli. And a sweet but not floral note, perhaps orange oil with rose geranium leaf? Honeysuckle, sage and sweetgrass.
Lalli: vetiver and sweetgrass with some sort of woody/smoky note, maybe cedarwood ? Sage or white sage. Peony or nenuphar. Frankincense, myrrh or Callitris resin. Chypre or labdanum. Bog myrtle leaf. And oakmoss.
Tuuri - a naive floral, maybe appleblossom, lilac and violet with an underlying bitter note, maybe both leaf and fruit oil of bitter orange. Black pepper. Vanilla, tonka bean or something else with coumarins.
Reynir - frankincense, vetiver, maybe lemongrass? Myrtle, wild rose with rosehip oil as well as flower oil, not the rich sweet attar of roses. Thyme and something sweet and totally out of place - jasmine? Lots of green notes, maaaybe galbanum?
