My New Dimension Idea!

my new dimension idea is called "The Overgrowth" so here's how it works: you start with one block.  To make the space around you bigger you need to collect materials and here are the items you need to collect:
Kudzu Loom - A Glowing Green Block That can Expand The Space Up To 15 Blocks

Amberbark -  A red and indigo (looks rich) block that can expand the space at least 35 blocks

Overcrust - The most colourful block in the dimension and can expand the space over 6000 blocks

and for the portal to get to the dimension you need to make it the size of a nether portal but just with Blue Concret and flint and steel to light it. Let me know what you think!
