i've just finished it! well i'm very happy with the result, made based on a cube 10x10cm (obviously jajajajaj) but i'm happy because i made this in just one day! i've just finished it! like 10 min ago.
this reminds me of the illustrations i saw in science books and stuff, showing different environments and types of soil and that kind of thing. i always thought it was really interesting to see the inside, since it was "cut" in the shape of a cube. the same thing happens here, i think it looks really amazing!
