Low-poly Pixel Art?! Whut [Art]

[LeleleleMAXIMUM]

mozzy: tbh, I haven't got the process down yet. Lots of trial and error. The colors you see on the renders aren't the colors I used in the bmp file. Meaning there's still some lighting messing with my colors.
And I don't know how to manage the edges.

But if you want, I can make a tutorial?
