MYOG Down Jacket

Hi Guys,
I've had a lot of free time lately so I thought I could sew a down jacket for use when hiking. I have very little sewing experience so I wasn't expecting to make something that would look good, just something functional that I could use to keep warm in Sydney winters when hiking.
The outer fabric is mainly made from a Argon 90, inner fabric and sleeves from Ion 15 denier, and the stuffing is 850fp down. The cuffs are made from scrap synthetic as I made the sleeves to short and ran out of down. Weight is exactly 250g, and the fill weight is 90g. All the material is from Tier gear.
The hood and waist has adjustable toggles to minimize drafts.
Welcome to suggestions for improvement.
