Agreed with the other anons—if you can't afford to sell these for less than $400, you need to find a way to reduce your costs (e.g. CNC plasma cutter) or else make them look a lot cooler. At $400 you need the prospective buyer to want what you're selling more than they want a plushie of their waifu. You're also competing with people like the guy who made >>42560278, who was selling 7"x7" waifu portrait window hangers for like $100 (which came with string and suction cups for hanging them up).

Yeah I bet they would look pretty cool with alcohol inks in the proper cutie mark colors (pic related, from https://www.trexinks.com/blogs/alcohol-ink-art-blog/tips-tricks-when-painting-alcohol-ink-on-metal). Or temper them to specific colors, though I think the range of colors you can get that way is more limited.

Might also be cool to make some of them two layers with a gap/spacer in between, for a sort of 2.5D effect. I'm mainly thinking of Twilight and Luna CMs which have distinct foreground and background elements
