A Trio of Twills

I ordered a set of yarns from Colourmart2, and am trying to make something cohesive with them.  The yarn came in five 250g skeins, and in an orangy-pink, brick red, red purple, brown and very dark red.  I spent way too long playing around with drafts, and finally decided to make the scarf in three broad stripes, with threading changes at the color changes.  The trio of twills are all variations on point twill.
