First off, you look great. I love the jacket, and combining it with the textured sweater is clever.
But on your comment that you "could not create more than one outfit without dark neutrals"--you have capsules of winter colors and winter light neutrals! With all the black and white patterns (permitted in the challenge) and solid color pieces, you could make lots of outfits:
-black and white patterned blouse/red trim from Esprit + red bottom (you have 3). Easy layup.
-jacket you're wearing + fuchsia Boden sweater (cheating and borrowing from your casual pieces) + Avery birdseye print pants
-brick red jacket (I love it) + Avery birdseye print pants or BR grey/black pants
-baby blue sweater + taupe or other light neutral bottom. I'm not good with light neutrals, but they don't have to stick together, can be mixed with colors
Really, any of the b/w patterns + any of the solid colors. I'd love to see outfits with the glen plaid jacket and red pencil skirt in action (obviously not together).
What I don't see are patterns in color. That makes it harder to wear 2 of the solid color pieces together.
But all of that is only because of your comment. If what you have on here is a true example of how you dress daily, I'm impressed & see no reason to change.
