Here's the stuff I put in:

stone sword and stone pickaxe textures are reversed

cooked steak is a really horrible looking pixelated child

oak log has been simplified

dark oak doors have been changed to the texture of dirt. This can be used to hide a door in the side of a hill

daylight detector has been simplified

enchantment table has been changed to green with amethyst instead of red with diamond

hay block has been simplified

glass is almost invisible with no boarder

bookshelves are empty😂

there's a smiley face inside of cake

minimalist diamond armor

zombies have the texture of dirt with grass

iron golems have no nose or unibrow, big weird red eyes and half of their right arm is gone

villagers have hair, no nose, and a dot for a mouth

drowned have green instead of blue on the inside

and finally, hearts are just multicolored lines

i will upload a MUCH better image gallery soon!

there is a very very very very very very very slight chance that the grass top will be grey. just tell me and i'll see if i can fix it
