Minecraft game started (Images attached below)

Yesterday, I started up my Minecraft game. I found 6 iron almost immediately and mined it. I used it to craft a shield and pickaxe. I later built a treehouse ( Which I will add some images of)

Me when I nearly died.
When it was starting to turn night, I found a river.
My inventory.
My treehouse when i made it
What the house was like just before I left the game. (The walls were wooden and the roof was still dirt)
