I’ve never made a pixel art before, and had no idea how to start this to begin with.
I started off with making a ground floor, middle floor and top floor, with a ceiling on top of it all. Then I made a isometric circle and rotated the middle floor on it, hand drawn frame per frame. It took me 6+ hours to complete fully, and another few hours to colour each frame in, frame per frame.
I am quite pleased with the results of this assignment, and I am glad I picked this, even though it was quite a hassle to get this house to turn.
