Nice work, as always, but you may want to fix the Alpha channel at the edges, for those of us using Dark Reader or similar tools that adapt/adjust web site look. See below how it looks, as compared to my own avatar (correct Alpha). I've noticed this happening on some hats, but not all. In fact, most are fine, just a few have rough/jagged edges.

Just a FYI, to make your near-perfect creations even better.
