(This is my first review so bear with me XD) This piece is quite exceptional, I must admit. I love how you divided the eight worlds into separate segments, kind of like a puzzle. It's also fascinating that you overlapped certain parts with the barriers. It makes it feel more life like and 3D. I also like how you put Mario in some and Luigi in others. Another thing is that it has kind of a patchwork/shoebox feel to it. Really toy-like, and that's a very good thing! It makes the peace more playful, colourful, and inviting! Very nice work! ^^ I love it!
