It's horrible. I'm very sorry, I don't know why it happened, I didn't display additional colors in Photoshop. I fixed this flaw.
It was very helpful of you to post your palette! I ran the picture through the site's Image Inspector and it looks like there's a good half-dozen 'non-transparent' colour slots, maybe an artifact from the context it was designed for; if you could see those cleared out of the image palette that would be great, thank you.
Reminds me of ps1 3d renders a bit. Like I get a big final fantasy 8 vibe from this. Nice stuff
