Frostlands Dimension

When I thought of a new dimension when all the other dimensions were done, I thought of a good one, the "Frostlands"!

Basically, it is both overworld, caves and floating dimension types, and the base block is a certain kind of ice called "Iceslate". The dimension has a kind of mob called "Creeping Frost". The Creeping Frost mob is a creeper that instead of exploding they breath out cold smoke that freezes you. The mob drops a kind of item called "Frost Powder". There is also a diamond ore variant of iceslate that drops 1 to 2 diamond shards when broken properly. You can craft a diamond using 4 frost powder and 5 diamond shards, in a crafting grid, shapeless, to get one. There are also trees that is made of a special wood called "Frost Wood". There are huts made of this type of wood and can contain a snow-type villager as either toolsmith, armorer, cleric, fletcher, mason, nitwit, shepherd or leatherworker. The dimension can be entered in and out with a kind of portal both just like the one for the end and the one for the nether. The frame for the portal is with compound snow that is crafted using 1 hardened powder snow, which is crafted using 4 powder snow, and 1 packed ice. To activate the portal you will need to place a blue compound snow using the same as crafting compound snow but with blue ice instead of packed ice, and throw an ender pearl at it and the blue compound snow will transform into the frostlands portal which you can go through to get to the dimension!
