Bubble Bobble - Layered Pixel Art

My first attempt at 3D pixel art since I recently joined the 3D printing world! I've made this guy before with plywood and paint, so I thought I'd see how he looked in PLA. Built him pixel-by-pixel in Tinkercad. He's layered for minimal waste, with my A1 and AMS Lite in mind. As this is my first attempt, I'm open to suggestions/constructive criticism. Hope you love him as much as I do!
