Update: Because this is unfinished, I recommend putting over top of a faithful 64 type texture pack that is cartoony, I recomment Vanilla XBR:

(I also do have another update that has been sitting in my ResourcePack folder for a while I should release, which will inevitably cause me to want to make more edits later, and then I will release those future updates in another year or so when I do this same thing agian. lol)

I decided to make my own texture pack, one that looked similar to default, but was HD and cartoony.
This is VERY work in progress.

The blocks I have made are:
All logs
Vines, grass
All leaves
All ores -quartz
All ore blocks (including quartz)
Dirt, grass, snow-grass and stone (including Diorite Andesite, Granite)
Ice, snowblock, snow covering
Cake
Polished Stone Blocks
Stone Brick Blocks, all variants (plus Nether Brick)
Cobble blocks and variants
Slime block
All glass, panes, and colored.
Wool, all colors.

Added all stone types and smooth stone types (Granite, andesite, diorite)

Added all stripped wood textures

Added netherrack and quartz ore blocks

Added double tall grass

Added redstone tile blocks

Added all colors of terracotta

Added all colors of concrete

Added Endstone

Added Obsidian

And more!

The items I have made:
slimeball

Added all ore items, made them correspond to their ore textures:

Diamond, Emerald, Coal, Redstone, Lapiz, Gold nugget, iron nugget, quartz

Mobs I have made:
Sheep

Sounds:

Changed one sound, see if you can find it in game without looking in the files. ;)

This was originally going to be just for me to use for fun, but then I noticed how great it is and decided to upload it to planet minecraft and curse forge.
