The mod's great, I love being able to customize it. If there's one suggestion I have is there could be sliders for every body part and not just specific ones like shirts and pants (being able to recolor your skin to green for example). This could be made optional with settings but I would love the option. I'd also love to have a template of the default Minetest playermodel beyond just Steve and Alex due to potential copyright concerns with Minecraft lol
Beyond that the textures are consistent, the color picker works really well where it's available, I like the base variety and being able to expand it more with mods is amazing! I wanna get my dirty hands and create more textures via the API more ASAP.
